Truffle butter is fresh butter which has been infused with white or black truffles. Use the flavored butter on grilled meats and fish, under the skin of poultry before you roast it or on steamed or grilled vegetables. It is also delicious in mashed potatoes. It can easily be substituted for butter in most savory recipes. There many commercially available brands which you can find in gourmet markets or online. You may find that the commercial products have added additional mushrooms such as porcini. If you wish to make your own please see our substitute below.
Truffle butter freezes very well and can be stored for a year or more frozen. Once thawed it should remain refrigerated and should be used within about 3 weeks. The flavor will continue to diminish as the product ages.
