Aromatically much less intense and delicate than the Black Truffle (Tuber melanosporum), stays a truffle with its scent approaching and slightly reminiscent of mushrooms and undergrowth. They're a little less lumpy than different truffle varieties (which is why they're referred to as Smooth Black Truffles), taking on a extra spherical shape. Slightly bit can go a great distance, so you don’t want to use too much, or you may wreck the dish. Saute the shallots flippantly in just a little butter. The steak was bursting with heat juice that ran like a river into the valley of melted truffle butter on the plate.
