Did You Know? Facts About Bittersweet Chocolate

There’s more to bittersweet chocolate than meets the eye! Here are some fun and lesser-known facts:

  • Contains fewer additives. Bittersweet chocolate is typically made with cocoa solids, cocoa butter, sugar, and a small amount of emulsifier. It rarely contains milk or flavorings, which keeps the ingredient list shorter than many sweeter chocolates.
  • High cacao = more natural compounds. Because it often contains 70 percent cacao or more, bittersweet chocolate is rich in flavonoids and other antioxidants that are linked to cardiovascular support when eaten in moderation.
  • Fermentation creates chocolate flavor. Raw cacao beans do not taste like chocolate. A carefully controlled fermentation process, usually lasting five to eight days, is essential for developing the complex flavors associated with bittersweet chocolate.
  • Works for sweet and savory dishes. Bittersweet chocolate pairs well with ingredients like sea salt, chili, citrus, and spices. Its natural bitterness helps balance rich or spicy flavors without adding excessive sweetness.
  • Performs better in baking. Many bakers prefer bittersweet chocolate for cookies, brownies, and cakes because its lower sugar content allows better control over sweetness and highlights cocoa flavor rather than masking it.
  • Stores better than sweeter chocolates. The low moisture content and absence of milk give bittersweet chocolate a longer shelf life when kept cool and dry, compared with milk chocolate.
