Dredge stuffed caps in flour, gently patting any excess, then coat in egg mixture. The look of truffles is deceiving-they don't seem to be attractive like other mushrooms with caps and gills. Truffles have a buttery chocolate center and are rolled in another ingredient, similar to cocoa powder or nuts. True chocolate truffles can have completely different flavors and be sprinkled with nuts as a substitute of being coated with chocolate powder on the outer shell. When you have a tough time deciding between a truffle or bonbon, think of a truffle prefer it has more chocolate and fewer filling and bon bons with less chocolate but extra filling. The chocolate shell is clean and might be spherical, oval, rectangular and even formed like a coronary heart. It has an off-white exterior, smells a bit like a baked potato and is said to the Périgord black truffle, a species typically used in high finish cuisine. While you finally spot a truffle, handle it with warning.
