Until the Bitter End
Science has classified flavors into five main groups, as perceived by our tongues. These groups are: Sweet, Sour, Salty, Bitter and -most recently- Umami.
Most foods and beverages have a combination of flavoring compounds that give them their particular “footprint,” that can encompass several of these flavor groups. This new series is devoted to the Bitter flavor, and to its impact on our everyday life.
Evolutionary scientists suggest that the ability to detect bitterness evolved as a way to protect us from toxic plants and other substances, which often taste bitter. Although it gets a bad rap, bitterness can be used to create well-rounded and desirable flavor palates. You may not be aware of it, but bitterness is present in many of our favorite foods including chocolate, coffee, wine and barrel-aged spirits.
What does the word “Bitter” mean?
Merriam-Webster dictionary defines the word bitter (when used as an adjective) as: being, inducing, or marked by the one of the five basic taste sensations that is peculiarly acrid, astringent, and often disagreeable and characteristic of citrus peels, unsweetened cocoa, black coffee, mature leafy greens (such as kale or mustard), or ale. The origin of the word goes back to Middle English, from Old English biter, going back to Germanic *bitra- (whence Old Saxon & Old High German bittar “acrid-tasting,” Old Norse bitr “biting, sharp”) and *baitra- (whence Gothic baitrs “sharp-tasting”), derivatives from the base of *bītan- “to bite.”
How Does “Bitter” Actually Taste?
Bitterness is neither salty nor sour, but may at times accompany these flavor sensations. Many people are innately opposed to bitter flavors, but a liking for it can and is acquired. Compounds that have an alkaline pH, such as baking soda, often have a bitter flavor.
Scientific research has found that some humans are more sensitive to bitter flavors than others.1 These individuals are referred to as “supertasters” and are often of Asian, African, or South American descent. Being a supertaster may explain why some individuals find the flavor of vegetables highly disagreeable. Most vegetables contain at least some bitterness, especially when raw.
Bitter Foods
Dark, leafy greens are well known for their bitter flavor. Green leafy vegetables often increase in bitterness as they mature. For this reason, many people prefer tender young greens to their more mature -and bitter- counterparts. Bitter green vegetables include kale, dandelion greens and broccoli.
Cocoa is another food that is enjoyed for its bitter flavor. Pure cocoa has a distinct bitterness, which can be used to balance flavors like sweet or spicy in other foods. Adding sugar and cream to cocoa significantly reduces its bitterness, making it more palatable.
Likewise, black coffee can be quite bitter. Although sugar and cream can be added to reduce the bitterness, many grow to enjoy the sharp flavor of black coffee. The type of bean and the unique roasting method will also impact coffee’s level of bitterness.
Citrus peels are well known for its bitterness, most of which resides in the white pith. As with most bitter flavors, it can be undesirable on its own, but when combined with other flavor elements, it can provide dimension and balance. Other fruits and vegetables that may provide bitter flavors may include grapefruit, bitter melon, mustard greens, and olives. Beverages such as tonic water, bitters, and mate tea are all also considered bitter. Before shying away from bitter ingredients in the future, explore how they can be combined with complimentary tastes to build a complex and enjoyable flavor profile.

Vanilla bean and Orchid
Featured Ingredient: Vanilla Bean
Scientific Genus: Vanilla planiflora
Vanilla planifolia traditionally grew wild around the Gulf of Mexico from Tampico around to the northeast tip of South America, and from Colima to Ecuador on the Pacific side, as well as throughout the Caribbean. The Totonac people, who live along the eastern coast of Mexico in the present-day state of Veracruz, were among the first people to domesticate vanilla, cultivated on farms since at least 1185. The Totonac used vanilla as a fragrance in temples and as a good-luck charm in amulets, as well as flavoring for food and beverages. The cultivation of vanilla was a low-profile affair, as few people from outside these regions knew of it.
Although the Totonacs are the most famously associated with human use of vanilla, it is speculated that the Olmecs, who also lived in the regions of wild vanilla growth thousands of years earlier, were one of the first people to use wild vanilla in cuisine.Until the mid-19th century, Mexico was the chief producer of vanilla. In 1819, French entrepreneurs shipped vanilla fruits to the islands of Réunion and Mauritius in hopes of producing vanilla there. After 1841, when Edmond Albius discovered how to pollinate the flowers quickly by hand, the pods began to thrive. Soon, the tropical orchids were sent from Réunion to the Comoros Islands, Seychelles, and Madagascar, along with instructions for pollinating them. By 1898, Madagascar, Réunion, and the Comoros Islands produced 200 metric tons of vanilla beans, about 80% of world production in that year. According to the United Nations Food and Agriculture Organization 2019 data, Madagascar, followed by Indonesia, were the largest producers of vanilla in 2018.(Source: https://www.wikipedia.com)
Did You Know That . . .
- Vanilla beans are hand-picked and then cured, wrapped, and dried in a process that takes 4 to 6 months. That’s a lot of time, but we believe it’s worth it! It is grown in a hot, moist, tropical climate, close to the equator.
- The spice we all love is one of the most expensive spices in the world after saffron.
- Only the melipona bee, found in Central America, can pollinate vanilla. In other parts of the world, humans duplicate the process using a wooden needle.
- One tablespoon of its extract has 37 calories, a large portion of which comes from sugars and alcohol.
- President Thomas Jefferson was the first American to bring vanilla to the United States in 1789.
