As any dog owner knows, putting eyes on your pup’s rear and pretending their tail is a nose is a source of much hilarity. But in Botswana, cattle farmers are harnessing this gag for good, in order to protect their cattle — both family food source and livelihood — from predation by local lions.
 
A four-year-long international study of cow/lion coexistence in the southern African nation has shown that stenciling large feline eyes on the back ends of cattle spooks lions into thinking their stealthy cover is blown — thereby sparing the life of the cow! From Gastro Obscura:
 
“‘We chose herds that had previously reported higher depredation rates, so we knew lions were a problem for them already,’ says [field researcher Cameron] Radford. Of the group, roughly a third were given a pair of furrowed, acrylic-painted eye-spots (‘We were going for the intimidation factor,’ says Radford), another third were left unmarked, and the remaining third received simple cross-marks. While 15 unmarked cows and four cross-marked cows were killed by predators, not one of the cows with eye-spots over the four-year study became big-cat food.”
 
Initially skeptical, the cattle farmers who had “donated” their herds to the study were soon converted, and eagerly adopted the low-cost method of keeping their cows safe. (In addition to themselves, and the lions: Retaliatory killings of the vulnerable big cats after cattle attacks were common.) This also safeguards their economic niche — cattle farming is the most profitable agricultural activity in Botswana, and over 95% of their beef is exported to other markets.
 
So it seems cattle/lion/farmer interactions are much like those between any other creatures — one part managing expectations, one part sleight of hand! I love the simple elegance of the study’s solution. And, as a BBQ fan, I’m glad the beef is saved!

Talmud incidences of measure (a visual concordance)

Scientists have been formulating “Frankenfoods” for decades now. There is validity to a certain amount of genetic modification; after all, we wouldn’t have today’s plump corn or watermelons or eggplants without selective breeding by ambitious (and hungry!) farmers over centuries. Nowadays, the GMOs we hear most about involving splicing genes from one incongruous species to another, which freaks some consumers out. But the unifying force in most of these attempts is the deliberate intention — which makes the news that scientists have accidentally created a new type of fish hybrid in an effort to save one of the parent species all the more surprising!
 
The task they set out to do was bolster the numbers of Russian Sturgeon, a fish prized for its caviar, but critically endangered due to overfishing, destruction of habitat, and pollution. A team of Hungarian scientists attempted asexual reproduction of the fish, using the sperm of another species, the American Paddlefish, to prompt the development of Russian Sturgeon eggs — a process known as gynogenesis.
 
Unfortunately, the Paddlefish and Sturgeon were genetically closer than the scientists thought, and instead of gynogenesis, good old-fashioned sexual reproduction took place, producing a hybrid now known temporarily (and cutely) as “sturddlefish.” And this may not be a bad thing:
 
“Each of the resulting fish look a little different, most of them bearing a stronger resemblance to the sturgeon (which was, of course, the whole idea). But if the offspring adopt the paddlefish’s dietary habits instead of the sturgeon’s, then the hybrid fish could greatly benefit the environment: Sturgeon have a diet of larger crustaceans while paddlefish feed on smaller organisms like plankton, making the latter’s diet more sustainable in the long run. (Microscopic organisms don’t have to be shipped in to feed the fish, meaning fewer carbon emissions.) Cheap diet + expensive roe = money in the bank.”
 
I’ve been doing a lot of reading lately about invasive species in my neck of the woods — so it’s refreshing that this particular goof in animal management might turn out well for a change.  And if it leads to stability for a food fish that we humans are responsible for destabilizing, all the better!

Here at the DFC test kitchens, David is the baker, while I fall decidedly into Camp Cooking. When it comes to baking, I usually only have patience for the sampling and critique of the results! David’s chocolate chip cookies are particularly legendary: as he did with our barbecue sauce, he spent years refining his recipe, experimenting with the chip to dough ratios and finely calibrating the sugars to yield the perfect chew.
 
But what he hasn’t done is engineer the ingredients themselves. Leave something that “disruptive” to chocolate-chip-cookieness to Tesla senior industrial designer Remy Labesque. He moonlights as a chocolate expert and has collaborated with California chocolatier Dandelion Chocolate to create the ideal baking chip.
 
While his chip still involves quality chocolate, Labesque’s innovation lies in its shape. The traditional teardrop shape is an artifact of the industrial process — it’s the easiest way for a machine (or a human artisan like Dandelion’s head pastry chef Lisa Vega) to fire out hundreds of chips in one go. But Labesque thought the dense, uniform shape lacked texture and was unsuited to the flat planes of a cookie. So, he set out to reconcile his dreams of the ideal melty cookie morsel to the industrial reality — or really, vice versa. The result: a modernist-looking, flat, faceted square chip, with two balanced pairs of thin and thick edges.
 
“At Dandelion, the design brief was to make ‘the best chip for the experience of tasting chocolate,’ says chef Vega. Experts claim the way to do that is to let it melt on your tongue.

Dandelion currently sells its ‘facets’ in three distinct, 70% single-origin, types: from Ecuador, Costa Rica, and Madagascar. Additional single-origin styles are planned for the future. The lengthy research and development and ingredient sourcing comes at a cost: a 17.6 oz. bag of the chips goes for $30.”
 
Coming from an IT background, I’m already a big proponent of “if it ain’t broke, don’t fix it.” I never thought that the chocolate chip was broke. Labesque and Vega have helped me rethink this — and I can never fault someone for following their passion, as niche and privileged ($30 USD a bag?) as it is. But none of us regular folks should let that stop our cookie perfection dreams: The original Depression-era chocolate chip cookie recipe used chopped up chocolate bars — it’s built to use what you have. A regular-shaped chip will never spoil a chocolate chip cookie, as long as you infuse the recipe with your own magic as well!

At the venerable Nathan’s Famous Hot Dog Eating Contest, this past July 4th, competitive eater Joey “Jaws” Chestnut set a new record in his chosen sport — 75 hotdogs consumed in ten minutes.
 
A team of sports medicine specialists have taken a closer look at Chestnut’s results with a key question in mind. That a very regular-looking human (his jaw doesn’t even unhinge!) can put away over six dozen tubes of processed meat at a rate of one dog every eight seconds is subjectively stunning; but how close is this feat to the objective upper limit of the sport? In short, is Joey Chestnut, in the words of study author James Smoglia, the “Usain Bolt” of hotdog-eating?
 
Turns out, he is. Smoglia’s team analyzed data from 39 years of the historic sausage gauntlet, using predictive mathematical modelling they usually applied to improvements in more traditional sports.
 
“Improvement curves in elite sports ranging from sprinting to pole vaulting tend to follow a so-called sigmoidal curve, featuring an initial slow and steady rise, followed by an era of rapid improvement and finally a levelling off. ‘Hotdog eating has definitely reached that second plateau,’ said Smoliga.”
 
After an early period where contestants relied on natural talent and how their stomachs were feeling the day of competition,

“[elite] eaters started to follow elaborate training regimes, with some ingesting vast volumes of liquid or gels to expand the stomach without having to process the calories. Chestnut, this year’s winner, claims to train for three months leading up to the competition, including weekly practice runs, a carefully controlled diet and yoga and breathing exercises to help with mental focus.”
 
This victory seems proof that really any action can be turned into a sport if training goes into it. But, like any other sport, there is a physiological limit to hotdog eating: by fitting the hotdog data to the rest of the sigmoidal curve, Smoglia and team predict that 84 hotdogs in ten minutes are the most any typical competitor can hope to eat, even with high-level training. Which makes “Jaws” Chestnut elite indeed!
 
While the condiment connoisseur in me winces at one of the best-loved barbecue options being relegated to so much world-record-fodder, I salute Mr Chestnut and his feat. I hope he gets the opportunity to sit down this summer next to a sizzling barbecue and enjoy a hotdog the way the grill gods intended — slowly savoured with a favourite topping or two. As I hope we all can!

As a mother of three boys, I was always put into a faraway room during my sons’ brit milah. So I’m not familiar with the actual procedure, just the after-effects. I had another family doctor attending my third pregnancy (long story not relevant here) who unlike my previous doctor was not Jewish. After successfully delivering my third son, this doctor when finding out we were passing on circumcision at the hospital, shyly asked if he could attend our son’s brit. Of course, I said yes (this was already my third and it was “old hat”).

I understand that during the brit ceremony my doctor unlike the other men, did not look away – he stayed back to be polite but was very attentive during the procedure. Afterwards, my doctor was so excited he related how “our way” of circumcision is almost foolproof as it is so uncomplicated compared to the modern surgical way of doing it with the Gomco clamp. He said that there were often many complications and whoopsies with the clamp method. I, of course, replied that we’ve had time to work out the kinks. This brit took place in the late 1980s and I am sure techniques in both the Jewish world & the medical world have changed and evolved, as things like this do.   

At DFC, we are well aware of how motivating food can be. After all, the prospect of bringing more delicious barbecue into the world was the main reason behind our own pivot to the condiment and sauce business!
 
There are many other species (including monkeys, octopuses, and dogs) that are just as keen as humans are to do extraordinary things for FREE SNAX.  But researchers have recently added an unusual animal — the hummingbird — to that list. And it turns out the teeny avian acrobat might actually source its meals with a truly amazing skill: counting.
 
Biologists at the University of St. Andrews set up a series of experiments with male rufous hummingbirds, who are known for their territoriality, and thus, long memories. They also have exhibited precise, repeated routes among nectar-heavy flowers in the wild, which indicated to researchers they had some way of knowing where the jackpot was.
 
“To find out, the researchers set up feeders with a nectarlike syrup in a valley in North America’s Rocky Mountains, just in time for the hummingbirds to start arriving in May. […]

To see whether the animals had a sense of numerical order, the researchers lined up 10 identical artificial flowers. They put syrup in the first flower and watched to see where the hummingbirds went to feed. Unsurprisingly, the birds went almost uniformly to the first flower, sometimes giving the others a quick check to see whether they also held a tasty treat.
 
Then, the team began rearranging the flowers after each visit, mixing them up — and even moving the entire line — so that the position of the flowers couldn’t give the birds information about which flower had the syrup. Even then, the birds chose the first flower in the line, suggesting they had a concept of “first.” And when the team repeated the entire experiment but baited, say, the third flower, the birds usually zoomed straight toward the third flower. This suggests they knew the third flower in line — regardless of where the line actually was — had the treat.”

This kind of spatial smarts results in an efficiency that must save so much time and effort in the wild. (Adjusting for body size, if a human were to eat as much as a hummingbird needs to in a day, we’d clock in at up to 155,000 calories! That is a lot of flitting around and sipping nectar!)

More research needs to be done, to determine if the hummingbirds are using any other hidden strategies besides counting. But the current results are promising — and testify to the power of food to spark the development of some amazing skills!
 

As summer hits its stride, we at DFC are enjoying keeping cool by any means necessary. Usually, a fresh breeze off the water greets us in the morning, but on particularly sultry days, I’ve found beating the heat needs to start as early as possible. This means I’ve retired my auto-drip for the summer and ventured out into the world of cold-brew coffee in search of my morning fix.
 
I learned a simple recipe: 1 cup coarse grounds floated in a pitcher of water and left to steep overnight in the fridge before filtration and enjoyment the next morning. But, as it turns out with all things food, there is a remarkably complicated lore behind the beverage. Nathan Silva at the food science blog Food Crumbles explains the science behind cold brew — including its legendary smoother taste.
 
“The main benefit most people will tell you there is with a cold-brewed coffee is the reduction in acidity. For a lot of everyday coffee drinkers, the acidic profile of most hot brewed coffees is an undesirable trait. This has caused cold brew coffee to boom in popularity. But is this ‘benefit’ actually real?

If you ask Megan Fuller, Ph.D., and Niny Rao, Ph.D., of Philadelphia University, the answer is: kind of. Through their research, they found that the same coffees brewed by both hot and cold methods, had a fairly significant difference in pH — an analytical measurement used to measure the acidity of a product. However, it was found that the roast of the coffee bean itself had a larger pH differential than the brewing method. So, choosing a good roast is has more impact than changing over brewing method. But if you’re stuck with one bean, the brewing method can help you get the desired acidity!”
 
Silva’s article is full of tips about brewing, bean choice, and even water temperature, which can be used to guide basically anyone to a balanced, perfectly cold glass of java. I’m going to refine my technique myself. I’m already sold on the time-saving aspects; now I juuuust want to get my coffee to barista-level flavour, so I never have to leave my sunny morning deck/workplace again!

In this space, we’ve looked at the many ways the future of pollination is in flux. While various types of bees and alternative pollinators like moths and bats are working hard, researchers are still looking to supplement their efforts artificially. (After all, the stability of the planet’s food supply is at stake) But humans with tiny brushes are clumsy and require payment, and bee-sized drones can bump into and destroy the very flowers they are trying to cross-fertilize.
 
The team that created those very drones set out to develop a gentler way to pollinate. What they have come up with almost belongs on a playground rather than a farmer’s field — soap bubbles! A study of the method was recently headed by Ejiro Miyako, associate professor in the School of Materials Science at the Japan Advanced Institute of Science and Technology, and published in iScience.
 
“After confirming through optical microscopy that soap bubbles could, in fact, carry pollen grains, Miyako and Xi Yang, his coauthor on the study, tested the effects of five commercially available surfactants on pollen activity and bubble formation. The neutralized surfactant lauramidopropyl betain (A-20AB) won out over its competitors, facilitating better pollen germination and growth of the tube that develops from each pollen grain after it is deposited on a flower. Based on a laboratory analysis of the most effective soap concentrations, the researchers tested the performance of pear pollen grains in a 0.4% A-20AB soap bubble solution with an optimized pH and added calcium and other ions to support germination. After three hours of pollination, the pollen activity mediated through the soap bubbles remained steady, while other methods such as pollination through powder or solution became less effective.”
 
The team loaded up bubble guns with the solution, then blew bubbles directly at pear flowers in an orchard, eventually successfully producing fruit. A further test involving artificial flowers and bubble-enabled drones showed a 90% “hit” rate with the drones hovering at 2 meters. All meaning this can work in the wild.
Though further tests and refinements are needed, blowing bubbles on a beautiful spring day may soon have a purpose beyond pure fun — it will support bees and other pollinators in their efforts to keep us alive!

For those of you who don’t eat pork or meat, this recipe is for you! The technique is easy and fun, and our original BBQ sauce is the perfect support for the flavour of king oysters in particular. Maureen, my daughter in law and a vegetarian was inspired to create something that was interesting, tasty and a crowd-pleaser for the summer BBQ season. 

When most of us hear “barbecue,” giant slabs of meat immediately float in front of the mind’s eye. However, there are increasingly tasty options available for vegetarians also popping up every season. This recipe is one of them: A Southern BBQ classic — pulled pork — is reimagined for the veg crowd with chewy and savoury king oyster mushrooms. The grilled, pulled mushrooms are finished with DFC Original Spicy Barbecue Sauce* and served on a bun with a bright, snappy red onion pickle. No more cobbling together side dishes for veggie friends at your barbecue!
 
* DFC Original Spicy Barbecue Sauce is entirely vegetarian. The Worcestershire sauce we use is anchovy-free, though (sorry, vegans!) the formula does include honey.
