October is the beginning of white truffle season, but if you have trouble finding white truffles, don't despair — these soufflés are delicious without them. Much of the deep flavor of this dish comes from Bra Tenero cheese. We tried lots of alternatives, and American Münster was the closest, though it won't turn the same golden brown color.
Cooks' note:
·Gnocchi can be boiled and drained 1 day ahead and chilled in 1 layer (without crowding) in a shallow baking pan, covered with plastic wrap.
