If you're buying a truffle or truffle oil for the first time, you'll want to know what you're getting. Black truffles are less expensive and have a softer flavor, often compared to earth, red wine, or chocolate. Physically, they're a little hardier and can stand up to heat, making them suitable for pizza, pasta, and truffle butter. White truffles have a strong ammonia-like scent but a flavor that can be rather garlic-like. More expensive and a little fragile, they're best used in delicate dishes, usually raw and shaved. Using white truffle-infused oil is a great way to get the flavor at a manageable price.
