Black truffles are the most famous in the world. The flavor of a truffle is pervasive in a subtle way; this enigma of taste is one of the reasons that truffles have such a loyal following. Give truffles center stage in your recipes. They are wonderful in omelettes, pates, soups and stews. Use in sauces made with cream, white wine or champagne, served over pasta, poultry or seafood. Add sparingly due to the potent flavor.
