Aromatically much less intense and delicate than the Black Truffle (Tuber melanosporum), remains a truffle with its scent approaching and barely harking back to mushrooms and undergrowth. They're rather less lumpy than other truffle varieties (which is why they're called Smooth Black Truffles), taking on a extra spherical form. A little bit can go a long way, so you don’t want to make use of too much, or chances are you'll break the dish. Saute the shallots evenly in somewhat butter. The steak was bursting with heat juice that ran like a river into the valley of melted truffle butter on the plate. To serve, pop solidified butter out of teacup the other way up onto a plate using a spatula.
