Bitterness

One of the basic tastes, a sharp, lingering flavor that bakers balance with sweetness, fat and salt.

Bitterness: A small arrangement of bitter dessert ingredients: a broken bar of very dark chocolate, a spoonful of cocoa powder, roasted coffee beans and a strip of orange peel
  • Food science and baking chemistry

In desserts, bitterness comes mainly from cocoa and dark chocolate, coffee, deeply cooked caramel, citrus peel and pith, some spices and over-toasted nuts. Too much baking soda can also leave a harsh, soapy aftertaste. A little bitterness adds depth and keeps a sweet dessert from tasting flat.

Bakers control it with balance. Sugar, cream and butter soften bitter notes, and a pinch of salt is known to reduce the perception of bitterness. Choosing a chocolate with a lower or higher cocoa percentage, stopping caramel at the right color and removing white pith from citrus are all simple ways to keep bitterness pleasant rather than harsh.
