  • Tempura is a staple in what many of us think of as Japanese cuisine. But how Japanese is this dish truly? 

    In actuality, tempura's roots came from Portuguese missionaries. When they arrived in Japan in the 16th century, they brought the style of coating food in flour, then frying it. When the Japanese saw this technique, they ran with it.

    Cut to Edo (Tokyo’s historic name) in the 18th century. It was one of the largest cities in the world, and was growing with a mix of people from different economic backgrounds. Specifically, during this peaceful period, many single Japanese men flocked to the city. 

    The food vendors needed a way to feed these bachelors quickly (and often cheaply), so food stalls and carts started becoming popular. This aligned with the introduction of tempura, whose (somewhat dangerous) frying process was better to do outdoors than inside. 

    Because fish was readily available in Edo, it became the popular base of the dish. It was then fried in sesame oil to eliminate some of the fishy smell. The vendors also started putting the tempura on sticks, to avoid the greasy fingers that followed enjoying the dish. Outdoor food courts are still very popular in modern Japan; the city of Fukuoka in particular is known for its open-air dining.

  • With a country of origin placed in the dessert's name, it seems as though the recipe for this coconut and pecan-filled chocolate cake obviously came from Germany. Right? Wrong. German chocolate cake isn't actually named after Germany at all. 

    Samuel “Sam” German invented a bar of sweet baking chocolate for Baker's Chocolate company in 1852. Although the company named the chocolate after its inventor, the name didn't reach legendary status until a Texas home baker sent her chocolate cake recipe to the Dallas Morning News in 1957. 

    The recipe apparently created a pretty delicious cake because Baker's “German's chocolate” sales skyrocketed the same year. Newspapers around the US republished the recipe for their readers, but the cake's name somehow lost the apostrophe-S in the republication process. 

    Germany now gets all the credit for this distinctly American treat, all because a man who had a country's name as a surname invented a bar of baking chocolate.

  • It's pretty common knowledge that a raisin is just a dried grape, but exactly how that grape is dried varies. In some instances, it's sun-drying, although the process can be lengthy. Artificial light and added heat often supplement the sun and expedite the desiccation.

    Putting grapes out to dry attracts insects and leaves the fruit exposed to dirt, sand, and other particulates. To combat bugs, many companies use pesticides, but they don't always dissipate or get washed off during processing. According to a 2020 report from the US Department of Agriculture, 99% of raisins sampled and tested were contaminated with two or more pesticides.

  • Children across the world may be devasted to learn that broccoli was, in fact, mankind's invention. But it wasn't just broccoli: cauliflower, kale, cabbage, and Brussels sprouts all stem from the same plant - a cruciferous vegetable in the Brassicaceae family (formerly called Cruciferae).

    What is this wondrous, amazing mother foliage? It's the simple wild mustard plant. But this simple plant evolved splendidly with selective breeding. Starting more than 2,000 years ago, farmers painstakingly chose different combinations to try. They reproduced the plants with the largest leaves (creating kale). They propagated plants with larger flower clusters, which they harvested before they bloomed (broccoli). From broccoli came cauliflower. And from cabbage came Brussels sprouts. 

    Successful efforts to make some of these mustard plant-derived veggies more appealing have resulted in an increased demand for Brussels sprouts. During the 1990s, Dutch scientists identified what made Brussels sprouts bitter and cross-pollinated versions of various bitterness to make more palatable varieties. 

    According to plant breeder Cees Sintenie, “from then on, the taste was much better. It really improved.” This may be why Brussels sprouts aren't the groan-worthy vegetables they once were. Demand for Brussels sprouts remains strong worldwide

  • A Common American Bread Ingredient, Also Used In Yoga Mats, Is Banned In Europe

    Bread is one of the most ubiquitous American foods, with entire grocery store aisles devoted to this one product. Of course, it isn’t just made from grain, and in the US at least, it also includes a variety of additives, typically to improve texture and color. Azodicarbonamide, for example, strengthens the dough and bleaches the flour.

    The compound also turns up in a wide spectrum of industrial contexts, including in the production of yoga mats. The European Union has thus banned its use in food products. There are 27 countries in the European Union as of November 2022.

  • The origin of mayonnaise is debated, but many stories about its birth are based in Spain. While the word is French, it's linked to Mahón, the capital of Minorca in the Spanish Balearic Islands, which were occupied by France on and off during the second half of the 18th century.

    At its core, mayonnaise is made with only three ingredients: raw egg, oil, and vinegar. The presence of raw eggs has led to assertions that mayonnaise can cause food poisoning with relative ease, but this has been overstated. Commercially prepared mayonnaise, according to experts, has such a high pH level that bacteria can't survive. In fact, research indicates mayonnaise may prevent or limit the growth of bacteria in food.
