Answer to Question 2

Chocolate is sold in different forms. Baking chocolate is chocolate liquor that has cooled and solidified in cakes. It is also sold as bitter, unsweetened chocolate. In any form, chocolate must have a chocolate liquor content of at least 35. Other possible ingredients include sugar, cocoa butter, lecithin, and flavoring.
Cocoa is chocolate liquor with most of the cocoa butter removed. This reduces fat to 10-24; the lower fat component gives cocoa a concentrated chocolate flavor.
