I try to keep my food simple and straightforward, and avoid anything sweet other than a few berries and a square of Lindt's Excellence 90 > cacao chocolate, but when I do want to make something special, this is my go to recipe site.
Chocolate is considered dark when there are little to no milk solids added to it and a high percentage (> 55 - 60 %) of the ingredients by weight are cacao solids.
