Swiss Gruyère is named for the valley of the same name in the canton of Fribourg. This moderate-fat, cow’s-milk cheese has a rich, sweet, nutty flavor that is highly prized both for out-of-hand eating and cooking. It’s usually aged for 10 to 12 months and has a golden brown rind and a firm, pale yellow interior with well-spaced, medium-size holes. It’s made in 100-pound wheels that are cut into wedges for the market. Gruyère is also produced in France and several other countries.
