Black Truffles and Truffle Juice

Tuber Melanosporum (Black Winter)
Also known as the "Black Diamond". Available November to March. These are 3/4 to 4 inches across with irregular shape, blackish brown in color, and marble red, brown interior.
Selected and pasteurized truffles retain their full taste and aroma.
These truffles are designated "brushed" which literally means they have been carefully cleaned and brushed, and are ready to use.

Tuber Aestivum (Black Summer). Available May to August. Resemble the Winter Truffles a lot, but are usually bigger and tougher. They are best used fresh. Black Truffles are also usually cheaper than the White because of their durability. Both can be preserved in oil or be frozen. Although less strongly flavored than the winter truffles, these are regarded as a fine dish ingredient by many truffle enthusiasts.
