Aromatically less intense and delicate than the Black Truffle (Tuber melanosporum), stays 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 shape. Just a little bit can go a long way, so that you don’t want to use a lot, or it's possible you'll break the dish. Saute the shallots frivolously in just a little butter. The steak was bursting with warm 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 utilizing a spatula.
