Aromatically much less intense and delicate than the Black Truffle (Tuber melanosporum), remains a truffle with its scent approaching and slightly reminiscent of mushrooms and undergrowth. They're rather less lumpy than other truffle varieties (which is why they're known as Smooth Black Truffles), taking on a more spherical shape. A little bit can go a good distance, so that you don’t need to make use of an excessive amount of, or chances are you'll break the dish. Saute the shallots frivolously in slightly butter. The steak was bursting with heat juice that ran like a river into the valley of melted truffle butter on the plate.
