Bellwether Farms Crescenza is a young cheese made of milk from Jersey cows that graze near the Callahan’s ranch in Two Rock, west of Petaluma. It is buttery, mildly tart, and shaped in a traditional Italian square form. Because it is such a young cheese, it does not have a long shelf-life. I developed this recipe specifically for crescenza, though you can serve these sautéed mushrooms with other creamy cheeses, such as teleme, ripe camembert, or brie. There are seasonal variations following the main recipe.
