Truffle salt will taste similar to the truffles they are made of, except they are a little saltier. The truffle taste is described as intense and earthy, however there are many varieties of truffles which can give distinct flavors. For instance, white truffle salts tend to be less sour, while black truffle salts possess more pronounced scent and taste. Most truffle salts you see on the market are likely to be made from black truffles.
