Bittersweet chocolate is a type of dark chocolate that contains a higher percentage of cocoa solids and less sugar compared to other chocolates. It typically contains at least 35% cocoa solids, but often ranges from 50% to 90% cocoa solids, with varying amounts of sugar.

The bitterness in bittersweet chocolate comes from the higher cocoa content and lower sugar content, which results in a rich, intense chocolate flavor with a slightly bitter undertone. It is commonly used in baking, cooking, and confectionery to add depth and richness to recipes.Bittersweet chocolate is often preferred by those who enjoy a more intense and less sweet chocolate flavor compared to milk chocolate or semi-sweet chocolate. It can be used in various desserts, such as cakes, brownies, truffles, and ganaches, as well as in savory dishes to add a hint of chocolatey richness to sauces or marinades.
