Monterey Jack, sometimes shortened to Jack, is an American white, semi-hard cheese made using cow's milk. It is noted for its mild flavor and slight sweetness.
In addition to being eaten by itself, it is frequently marbled with Colby to produce Colby-Jack or with yellow cheddar to produce cheddar-Jack. Pepper Jack is a version flavored with chili peppers and herbs. Dry Jack is a harder cheese with a longer aging time.
The cheese is commonly used as an interior melting cheese for California-style burritos, but also some Mexican-style burritos ("bean and cheese"). It can also be used on pizza or for grilled cheese sandwiches. It has a mild flavor and good melting quality for some pasta dishes.
Because of its low content of tyramine, an organic compound thought to be associated with headaches, Monterey Jack is frequently recommended as one of the few kinds of cheese that is safe to eat for migraine sufferers.
