Umbria is a famously lush region in central Italy, known for its olive oils, wines, and dairy, among much more. For this selection, fresh butter from grass-fed cows is churned with White Winter Truffles to produce a luscious, subtly piquant butter that marries beautifully with myriad accompaniments. On their own, the White Winter Truffle flavor profile eludes easy summary — they’re garlicky, with a rustic barnyard funk reminiscent of exquisite cheese and a caramelized nutty sweetness that melts marvelously into fat, the very trait that makes this butter such a stellar staple to have on hand.
