Because bittersweet chocolate is high in pure chocolate (at least 35 percent cocoa solids), it's best used when a deep chocolate flavor is called for. It's also a great eating chocolate. Semisweet chocolate, which has more sugar and fewer cocoa solids than bittersweet, can often be substituted in recipes without significantly affecting the flavor or texture.
The BEST Chocolate Cake with Chocolate Mousse Filling! My favorite chocolate cake recipe with dark choc mousse fillling and warm frosting poured on top! AMAZING! Recipe from TastesBetterFromScratch.com:
French Silk Pie. I have tried many French silk pie recipes, and this one is the easiest and the tastiest! I love the fluffy, rich chocolate mousse with the homemade whipped cream. This is one of the best desserts you will ever make! There is never any leftovers and I always get asked for the recipe.
Many of the fine-quality bittersweet chocolates sold at supermarkets typically contain 50 to 60 percent cocoa solids. If you choose chocolate with a higher percentage, your mousse may be slightly denser.
