Brie is a cheese that can be so mild and firm that even children like it despite the mushroom-like flavor and the white mold that gives it its velvety rind. If aged for long enough, it can also be very funky and downright runny—the mold works its magic all the way inside the wheel. With this dairy-free version, we find a balance by using aromatic black truffle salt and white truffle oil in order to enjoy that earthy flavor that aging and mold create. We never age this Brie, but we can make it taste and even look as tempting and inviting as the real thing. Truffles can be an acquired taste, so feel free to explore the variations if your palate prefers an alternative! Note: Leave the agar powder out completely for a delicious melty version of this cheese.
