Unsweetened chocolate, as its name indicates, contains absolutely no added sugar, while bittersweet chocolate has anywhere from about 10% to 50% sugar. Because of the difference in sugar content, these two types of chocolate are not interchangeable in recipes.
Can i add sugar to unsweetened chocolate to make it bittersweet?
YES! You adjust a tablespoon of sugar for each ounce of chocolate. In this case. If you’re using unsweetened instead of bittersweet, add 1 tablespoon of sugar per ounce of chocolate and vice versa.
