According to Wikipedia, Bittersweet chocolate is chocolate liquor (unsweetened chocolate not liqueur) to which some sugar (typically a third), more cocoa butter, vanilla, and sometimes lecithin has been added. It has less sugar and more liquor than semisweet chocolate, but the two are interchangeable in baking. Bittersweet and semisweet chocolates are sometimes referred to as 'couverture' (chocolate that contains at least 32 percent cocoa butter); many brands (the ones I like) print on the package the percentage of cocoa (as chocolate liquor and added cocoa butter) contained. The rule is that the higher the percentage of cocoa, the less sweet the chocolate will be. The American FDA classifies chocolate as either "bittersweet" or "semisweet" that contain at least 35% cacao (either cacao solids or butter from the cacao beans).
So using this definition, almost any of my recipes will work since I use mostly very dark chocolate.
As in any of my recipes, the quality of the ingredients will make a difference in the flavor of your final product. I often have left-over chocolate (I know, who has left-over chocolate? I do), and I like to combine different brands of chocolate and amounts of cacao in this recipe--both in the melted chocolate part of the recipe and in the chunks that are folded in later. Very fun and yummy! Also you can also substitute brown sugar for white, but you'll have a different cookie!
Happy Bittersweet Chocolate Day!
