Tuber aestivum, the mild summer truffle is found in central and northern Italy, Spain and Eastern Europe. Black on the outside, with pale flesh, ranging from cream to grey as the truffle matures. More delicate flavor than either the Burgundy or the black winter truffle, summer truffle is harvested from May to September and bottled in truffle juice to lock in the flavor and aroma, and thus can be used throughout the year.
The summer truffle is less expensive than the Winter black truffles. Julienne and add to a salad. Shave thinly and serve raw or slightly warmed to protect the delicate flavor. Layer truffle flavors by using truffle butter or truffle oil in your recipe, and fresh shavings of summer truffle as an accent.
