It's BLOOMING hot out here! What to do with bloomed chocolate.

By: Cecily Costa


Well #$@& happens and especially with all the hot weather we have received in the past few weeks, chocolate will bloom. But most importantly, don’t throw it out!

Chocolate bloom is a white powdery surface due to fat bloom or sugar bloom. This problem is due to incorrect storage of chocolate; either too warm or too cold. Fat bloom occurs when cocoa butter either does not crystallize properly or undergoes a phase transition when stored in warm or humid conditions. Fat bloomed chocolate feels 'oily' or 'greasy' due to surface layer of fat. Fortunately, fat bloom can be reversed by either tempering the chocolate or using it in a baked good where the chocolate will be warmed or cooled in similar way of the tempering process.

Sugar bloom occurs when sugar dissolves in surface moisture and recrystallizes, so do not store unwrapped chocolate in the fridge. Sugar-bloomed chocolate feels 'grainy' due to sugar deposits on the surface. Most importantly, sugar bloom is irreversible, so sugar-bloomed chocolate cannot be fixed (though you may be able to salvage it in a brownie recipe).

Chocolate with low cocoa butter content (like 32%) will have less than high cocoa butter content couvertures. If the chocolate is being used in baking (either as a chip or melted into the recipe) the quality won't be affected. If you are making molded truffles, the chocolate will need to tempered again.

Why We All Scream When We Get Ice Cream Brain Freeze

By: Ashlie Stevens, July 31, 2017—the salt, NPR

Brain freeze — its technical name is sphenopalatine gangli on neuralgia. This is the signature pain of summer experienced by anyone who has eaten ice cream with too much enthusiasm or slurped down a slushie a little too quickly. It's enough to get most people to stop eating the ice cream all together.

Dr. Kris Rau of the University of Louisville in Kentucky, says it's a good way to understand the basics of how we process damaging stimuli. "Now on the roof of your mouth there are a lot of little blood vessels, capillaries," Rau says. "And there's a lot of nerve fibers called nociceptors that detect painful or noxious stimuli."

The rush of cold causes those vessels to constrict. "And when that happens, it happens so quickly that all of those little pain fibers in the roof of your mouth — they interpret that as being a painful stimulus," Rau says. A message is then shot up to your brain via the trigeminal nerve, one of the major nerves of the facial area.

The brain itself doesn't have any pain sensing fibers, but its covering — called the meninges — does. "And of course all of those little pain-sensing fibers are hooked up to your trigeminal nerve," Rau says. "So the brain is trying to figure out what is going on. It knows there is something wrong, something that is painful and they don't know exactly where it is."

And the pain message finally registers at the top of your head, which seems kind of random. "But it's a very similar phenomenon to the referred pain that is experienced by people who have heart attacks," Rau says. "You don't feel like your heart is hurting itself; it's your shoulder that is starting to hurt on your left side." And after a minute or two, the brain and body go back to normal.

Interestingly, Rau says there is anecdotal evidence suggesting that ice cream headaches might be an effective treatment for migraines. It does not work for everyone, but at least it might be worth a tasty shot!

Healthy Eating Department - Why The Arctic Apple Means You May Be Seeing More GMOs At The Store

By: Grant Gerlock, NPR the salt, February 1, 2017

Genetically engineered crops are nothing new. But emerging technology that allows scientists to alter plants more precisely and cheaply is taking genetically engineered plants from the field to the kitchen.

The first version of the Arctic Apple, a genetically modified Golden Delicious, is headed for test markets in the Midwest in February, according to the company that produced it. It is the first genetically engineered apple, altered so that when it is cut, it doesn't turn brown from oxidation.

Okanagan Specialty Fruits, based in British Columbia, Canada, wouldn't say exactly where the apples will first be sold, but says the target consumers are those interested in convenience. "The rapid expansion of the fresh-cut industry – bagged carrots, ready-made salads – has led to explosive growth of fresh cut produce," says Neal Carter, president of the company. "I can cut this up for my kid's lunch box ... and it doesn't go brown and they'll actually eat it."

The Arctic Apple is one of the first foods often termed a "genetically modified organism" (GMO) to be marketed to consumers, not at farmers. And it's a sign of how the science of genetic engineering is evolving. The first genetically engineered crops were global commodities like corn, soybeans and cotton. They were "transgenic," meaning they were resistant to pesticides or insects after scientists transferred new DNA into the plants.

"We were taking DNA sequences from another, often non-plant species, and moving it into plants," says Sally Mackenzie, a plant geneticist at the University of Nebraska-Lincoln. In contrast, new crops are "cisgenic." They work within a plant species' own genome. "The next generation of technologies, those being implemented now — including the new apple – we're not introducing foreign DNA any longer," Mackenzie says.

The Arctic Apple uses a technology called RNA interference, sometimes called gene silencing. The target is the gene in the apple that controls production of the enzyme that makes it turn brown. When scientists add an extra strand of RNA, that gene is effectively switched off, or silenced. "We're basically down-regulating a gene that's already within that apple," Mackenzie says. "So I see that as entirely different. And I think it's important for the average consumer to recognize technologies have moved on."

Advances like gene silencing and other gene editing methods, like CRISPR technology, make biotech plant-breeding cheaper and more precise than the first generation of genetically engineered crops. New technologies are also less expensive for companies when it comes to federal regulations, as the U.S. Department of Agriculture and the Food and Drug Administration require fewer costly tests.

Huge companies like Monsanto have dominated the industry, Mackenzie says, in part because of the high cost of regulations. Old biotech crops were aimed at big commodities in large part because it was a sure way to recoup that investment.

Engineered plants that don't introduce new genes don't face the same regulatory hurdles. Groups critical of GMO technology want to see stronger regulations in order to evaluate potential long-term impacts of biotech crops on health and the environment. Federal agencies are reviewing their rules around GMOs to catch up with the technology.

Under the current regulatory structure, however, it is more economically viable, Mackenzie says, for smaller biotech companies to market their own innovations. "You're going to see more and more traits coming out that are really consumer friendly, designed to respond to consumer demand," Mackenzie says. Corn will still get plenty of attention from plant breeders, but more companies may shift their focus from field to fridge.
Most genetically engineered crops are processed into ingredients in foods, so when we eat them they are a few steps removed from the field – think soybean oil in salad dressing or corn syrup in soda. When the Arctic Apple hits the produce aisle, however, it will be one of the first GMOs to reach consumers directly, but it is not the only one. A virus-resistant Rainbow papaya is already on the shelf. So is Simplot's bruise-resistant russet, called the Innate potato. The fruit company Del Monte has approval for a pink pineapple engineered to carry more lycopene, an antioxidant that supports the body's defense system.

The labels on packages of Arctic Apples won't say much about GMOs. They will have a tell-tale snowflake logo, and a QR code that can be scanned with a smartphone to reach a website with information about the science. That fits within the framework of a GMO labeling law passed by Congress last year, but it makes genetic engineering in food less obvious than many consumer groups have called for. The vast majority of consumers support clear labels on foods that contain GMO ingredients, just as the vast majority of scientists agree that they are safe to eat. For stores that may sell biotech fruits and vegetables, it pays to be up front with shoppers that these foods are genetically engineered.

"Transparency is what everything is about," says Joan Driggs, editorial director of Progressive Grocer which covers the grocery business. "Any retailer or manufacturer has to be transparent with their customer." The big question for the biotech industry: Once consumers know how these apples are created, will they care?

The Arctic Apple's test run will last through March. Okanagan Specialty Fruits expects a wider commercial release this fall.

Grapefruit & Salt: The Science Behind This Unlikely Power Couple

By: Cecily Costa

Taken in part from NPR, the Salt (November 14, 2016—Nadia Berenstein)

Ad campaigns from the first and second world wars tried to convince us that "Grapefruit Tastes Sweeter With Salt" as one 1946 ad for Morton's in Life magazine put it. The pairing, these ads swore, enhanced the flavor and there's science to prove it.

The origins of our grapefruit habit—
Grapefruits originated in Barbados in the middle of the 18th century. They are a hybrid formed from the Javanese pumelo and the East Asian sweet orange. First grown commercially in Florida at the end of the 19th century, grapefruit quickly went from being a novelty to being a daily necessity and made fortunes for farmers.

Early 20th century cookbooks and recipes in magazines offered an abundance of ways to use grapefruits in sweet confections, as well as in savory-sweet salads. But the most common option was the one that's still familiar to us today — at breakfast, chilled, sliced in half, sprinkled with sugar and (optionally) crowned with a bright-red candied cherry.

In 1911, an Iowa woman calling herself "Gude Wife" wrote in to the "The Housemother's Exchange," a national advice column, to recommend salting grapefruits. "Salt neutralizes the bitter taste as well as the acidity," she advised. Others wrote in to back up this endorsement. "I think you will find that many Southerners always salt their grapefruit," wrote "M.B.L." from Philadelphia. "I am sure that if you once try it you will agree with me that it is good." In fact, salting fruit remains a regional practice alive and well in the South.

Go salty for Uncle Sam—
But when World War I disrupted the global sugar supply chain, causing sugar shortages and skyrocketing prices, grapefruit sales plummeted. Americans were apparently reluctant to eat the fruit if they couldn't drown out its pungency with sugar.

Panicked, the Florida Citrus Exchange, in an effort to boost sales, launched a national advertising campaign in 1919 to convince Americans that grapefruit "need no sugar, and never should have much." After the sugar crisis ended, so did the campaign. But when World War II came along, and sugar once again became scarce, salt and grapefruit's high profile romance was rekindled — this time by salt manufacturers. "Vitamin-rich Grapefruit — a 'Victory Food Special' — is one of the fruits Uncle Sam advises you to eat," explained one 1943 ad from Morton's Salt.


Ads like this made an overt appeal to patriotic sentiments. Eating grapefruit with salt was a way civilians could support the war effort, both by consuming nutritious, domestically grown food, and by limiting their use of rationed sugar. The campaign proved so successful that it continued into the 1950s, long after rationing had ended.

The science behind adding salt for sweetness—
Even as salt-makers boasted about the taste-enhancing effects of salt on grapefruit, they were at a loss to explain just why the combination worked. It wasn't until the mid-1990s that Gary Beauchamp and Paul Breslin at the Monell Chemical Senses Center in Philadelphia began to unravel the complex, dynamic process through which salt transforms and enhances flavor. By testing the interaction between three taste sensations — salty, bitter and sweet — they found that salt increased the perception of sweetness by diminishing our ability to taste bitterness. Beauchamp, now emeritus director of Monell, explains that this is because of the ions in the salt, which block many of the receptors on our tongues that detect bitterness.


But would reducing bitterness make something taste sweeter? Our sense of taste doesn't just play out on the surface of our tongues. Our brains receive signals about what we eat from our mouths, noses, eyes, ears and skin, integrating and interpreting these different messages to produce the complex, multi-sensory experience that we know as flavor. There is strong evidence that, at this cognitive level, bitterness and sweetness inhibit each other. In other words, the more bitter something tastes, the less sweet we perceive it to be, and vice versa. Grapefruit is rich in bitter-tasting plant compounds, especially one called naringin. By diminishing our tongue's ability to sense naringin and other bitter compounds, salt also produces a secondary cognitive effect, which we perceive as "a relative bump in sweetness," according to Breslin, a professor of nutrition at Rutgers University.

Something else might be going on, too, he says. Salt changes the chemistry of water. In a watery food like grapefruit, the addition of salt makes it easier for volatile molecules — the chemicals responsible for odor — to launch themselves into the air, where we can breathe them in and smell them, intensifying our experience of the fragrance of the fruit. So that enhanced scent might heighten our enjoyment as well.

Yet other cultures have long embraced the beauty of pairing salt and fruit. In Mexican and border cuisines, it is common to douse fruits (especially mango) with a combination of salt, chili powder and lime. Similarly, salting fruit like guava or, say, an unripe mango is common practice in India. Thai prik-kab-klua combines salt with the heat of fresh red chilies and sugar, and is served on tart fruits. Chinese li hing powder, a puckery mauve mixture based on salted, pickled dried plums, is often sprinkled on apples and pineapples.

This ain't your grandma's grapefruit—
Why does the practice remain relatively uncommon in the U.S. now? In the case of grapefruit, the explanation may lie not with the salt, but with the fruit. We are eating different kinds of grapefruit than Americans were eating in the 1940s and 1950s. Generally speaking, as the 20th century progressed, grapefruits became redder, sweeter and more completely seedless. Currently, about three-quarters of the grapefruits that we eat are red. Redder grapefruits contain less naringin, and therefore taste less bitter. This means that there is less of an incentive to curb bitterness with a dash of salt.

So, if you have never salted your grapefruit, give it a try—you might find you like it!

Healthy Eating Department - Why is High Fructose Corn Syrup so scary?

Recently, a UCSF researcher stumbled upon the fact that, back in the 1960’s, the Sugar Research Foundation (now the Sugar Association) paid three Harvard scientists to minimize the link between sugar and health suggesting that saturated fat is more the problem. Now we are learning the reverse is true. And, not all sugars are created equal. Here’s the breakdown...

Regular cane sugar (sucrose) is made of two sugar molecules bound tightly together—glucose and fructose in equal amounts. (50/50). Glucose is our main fuel source for energy. Glucose is a simple sugar in foods that are easily broken down by every cell in our body. The enzymes in our digestive tract break down the sucrose into glucose and fructose, which are then absorbed into the body. Natural fructose, from fruits and vegetables, has good nutrients and fiber to slow down digestion and make us feel full. Fructose the ingredient, is digested so quickly you don’t feel full and you eat more. More importantly, it contains no essential nutrients and is completely “empty” in calories.

High Fructose Corn Syrup (HFCS) is bad because it consists of glucose and the ingredient fructose, not in a 50-50 ratio, but a 55-45 fructose to glucose ratio in an unbound form. Since there is no chemical bond between them (glucose and fructose) no digestion is required. The glucose is rapidly absorbed into the bloodstream and the ingredient fructose is metabolized in the liver and triggers lipogenesis (the production of fats like triglycerides and cholesterol). This is believed to be the major cause of liver damage in our country and causes a condition called “fatty liver” which affects over 70 million Americans. Dr. Joseph Mercola, a NY Times best selling author and personality states that HFCS is as dangerous to the liver as alcohol. The ingredient fructose can cause visceral fat accumulation—the worst type of body fat. It’s also linked to health issues such as diabetes, heart disease, body-wide inflammation and obesity.

Dr. Mark Hyman, MD—best selling author on nutrition and wellness, and a regular on PBS—states that HFCS and cane sugar are NOT biochemically identical or processed the same way by the body. HFCS is an industrial food product. The sugars are extracted through a chemical enzymatic process resulting in a chemically and biologically novel compound called HFCS. HFCS contains contaminants including mercury because of chloralkali products used in its manufacturing and are not regulated or measured by the FDA.

The USDA reported the ANNUAL average for sugar consumption in the US in 2013 was 128.4 lbs per person and that corn sweeteners made up over 55% of that (58.6 lbs per person). That is a staggering number. The USDA recommends a 2,000 calorie diet include no more than 40 grams (1.5 oz) of added sugar per day (that’s about 10 teaspoons a day, or 32 lbs a year!). That’s a long way from caveman days when our hunter gatherer ancestors consumed the equivalent of 20 teaspoons per year.

Products with HFCS are sweeter and cheaper than products made with cane sugar. To be fair, HFCS is not the same as pure corn syrup; but corn syrup is GMO, which is another issue altogether. Interestingly, Karo Corn Syrup in retail is pure corn syrup while the foodservice product is HFCS. What can you do? You could use cane, agave, maple syrup and raw honey if you want a better liquid sugar. These products might cost you more, but they are healthier. Our health matters!

Healthy Eating Department - Gluten-Free is Not a Fad

By: Cecily Costa

Though an estimated 1% of Americans have celiac disease (about 3 million people), US News & World Report believes approximately 6% of the US population have “gluten sensitivity” (headache, eczema, tingling of extremities, iron deficiency, allergies, internal discomfort...the list goes on). That means about 7% of customers, twice the amount of people who eat vegan, eat gluten-free. Gluten sensitivity is even believed to be linked to autism and other autoimmune diseases. 

Until recently, people with gluten sensitivity did not test positive for celiac. But, this past July, UPI reported that researchers at Columbia University Medical Center confirmed that people without celiac disease can experience a body-wide immune response to wheat thought to be related to intestinal cell damage and a weakening of the intestinal barrier. Translation—people with a wheat sensitivity, but not celiac disease or a wheat allergy, are not imagining symptoms they feel after eating wheat, according to this new study.

It wasn’t long ago that most restaurants didn’t even have a vegetarian option on the menu. Vegetarian dishes were done on the-fly without much thought or finesse. Now there are all sorts of great meatless options on menus everywhere and most of these dishes are more profitable for operators too! Hello 2016. 

How many of your menu items reflect gluten-free options? If the answer is zero, you might want to consider adding a few gluten-free options, or better yet, tweaking some of your existing recipes by just switching out one item (see below for some easy ideas). 

A 2015 Gallup poll found 20% of Americans were including gluten-free foods in their diet and a 2014 Consumer Reports survey found ⅓ of adults where trying to cut gluten from their diets. And if that is not enough to show what a strong trend the gluten-free market is, the US retail packaged food market has grown to $1.77 billion in 2014. That’s a huge number! Regardless if you think gluten free is a fad, or that some items are just marketing themselves as gluten free for publicity, you can’t deny the powerful impact this is having on our economy. 

Speaking as a gluten sensitive person, I can’t tell you how challenging it can be to dine out at a restaurant where there are few to none regular menu options and the wait staff is uninformed . I went to one restaurant recently where they had a totally separate menu for gluten and dairy allergies! This took the stress off me and the waiter, and I can’t help but think of the relief the kitchen feels from not have as many special orders—hat’s off Stark Restaurant Group!! 

So get on board the gluten free train, it will satisfy the needs of your customers, and also your bottom-line!

What’s all this talk about canned tuna from Sausalito?

By: Cecily Costa


There is a new tuna on the market (Safe Catch) that is getting some buzz thru a lot of radio ads and marketing regarding Mercury testing.

I have been asked by a few customers and sales rep about them so I would like to share what I know. For the sake of this article, I will compare them to our highest quality and domestically produced albacore tuna on the market—Oregon Seafoods.
  • Safe Catch is not domestically produced. Their office is in Marin, and the tuna is packed in Thailand. They produce “Elite” (Skipjack) and Albacore.
  • Safe Catch albacore tuna is harvested in northern Pacific and southern Pacific oceans. Oregon Seafoods is a domestic product fished off California, Oregon and Washington waters.
  • Safe Catch proudly states it is high in Omega 3’s and lists a fat content of 1.5 grams per serving. Oregon Seafoods fat content is 6 grams per serving. The higher the fat, the better! Higher fat content also reflects the content of healthy Omega 3’s.
  • Safe Catch markets their tuna as better protein at 35 grams per can—that’s 14 g per 2 oz serving. Oregon Seafoods has 16 grams of protein for the same size serving.
Mercury testing each individual tuna may seem like a game changer, but it does not tell you the whole story. It seems they have new proprietary equipment to test each piece of tuna for Mercury, which is different. Currently, the industry standard is to test schools of fish on a regular basis.

They claim their albacore testing is 3x stricter than the US FDA’s 1.0 parts per million (ppm). That would come out to .33 ppm. Currently the industry standard for albacore is .33 ppm. Below is a chart from The Safina Center (formerly Blue Ocean Institute) in New York, a well respected non-profit sustainable seafood program (more at www.safinacenter.org).



The Safina Center also discovered that sunlight in shallow waters of the Pacific Ocean can destroy up to 80% of methyl-mercury in fish. Conversely, in the deep oxygen-poor water, bacteria are converting significant amounts of mercury to the problematic methylmercury. This is why fish that live and feed in deeper waters have more mercury in their system.

The industry now believes that as long as there is MORE selenium than mercury in tuna, you are fine. Basically, it is Mother Nature’s way of taking care of balancing things out.

Both the Western Pacific Regional Fishery Management Council (www.wpcouncil.org) and the Canadian Highly Migratory Species Foundation (CHMSF www.canadianalbacoretuna.org) have published information regarding selenium, see chart below. 

So, how does mercury get into our food supply? Mercury is naturally occurring from volcanic activity and weathering of rocks, and human activities like mining and fuel. Once released, mercury enters air, water and soil, and moves from one to another until it comes to rest in sediments or landfills.

Albacore tuna typically live up to 10-12 years in the warmer south Pacific. Domestic (north Pacific) albacore tuna is caught in more shallow, colder waters where the fish harvested are typically 3-4 years old and weigh 7-24 lbs...too young to have accumulated harmful levels of Mercury. Oregon Seafood's albacore is between 3-5 years old.

All fish have some trace amounts of mercury, most fish have less than 0.1 parts per million (ppm). The general rule of thumb is that the larger or older the fish, the higher the level of methylmercury in its flesh. Up until recently, mercury content of tuna was averaged for all species, making no distinction between small, young albacore from the cold north Pacific and the much larger, older tuna from the warm south Pacific. So Oregon State University researchers sought to compare mercury content among all the major commercial species of tuna. They found that small, young albacore tuna caught off the Pacific Northwest coast have low mercury levels, below most commercial brands and below FDA guidelines. In fact one test by the Oregon Albacore Commission and the Western Fishboat Owners Association had mercury levels at 0.14 ppm (that is HALF what the other tuna is advertising).

Traceability—it is difficult for the FDA to police the tuna industry worldwide. In many areas it is self-governed. The strictest controls for responsibly fished tuna comes from domestic producers (fished, packed and processed in the US). Fish that is harvested in Asia and India is at best spot checked for origin, species and by-catch. Oregon Seafoods is proudly fished, produced and packed in the US. They buy directly from family fishing boats that take care of their catch. They pay living and fair wages to their employees and fisherman. All of their product is traceable down the to boat and day. They don’t have extra marketing dollars for radio or print ad campaigns. The put their monies into producing the best tuna available on the market.

I did a cutting of a 5 ounce can of Safe Catch and another domestic albacore tuna the other day. The most surprising result was the drained weight of the Safe Catch was 4 ounces. The drained weight of the other brand was 4.8 ounces. And the Safe Catch tuna was more expensive.

Let me show you the difference of Oregon Seafoods and tell you who has it on their menu. Contact me today for a cutting. See and taste the difference!
