Sauce Financière with Truffle Spheres

Sauce Financière is essentially a Madeira sauce flavored with truffles. Everything is done to preserve the truffle aroma and flavor. The sauce contains truffle juice that hasn’t been reduced, so that none of the precious perfume has evaporated. Truffle butter is sometimes used to mount the sauce with butter. Truffle spheres offer an entirely new way of delivering the truffle flavor without concern that it will evaporate or volatilize. Here, this luxurious sauce is served atop a tasty steak.
