Monterey Jack was first made by 18th-century Franciscan friars in Monterey, California
Monterey Jack, sometimes shortened to Jack, is a Californian white, semi-hard cheese made using cow's milk. It has a mild flavour and slight sweetness. It was first made by 18th-century Franciscan friars in Monterey, California.
In its earliest form, it was known as 'Jacks' Cheese' and was sold commercially by California land speculator and businessman David Jacks. It eventually became known as 'Monterey Jack'. It is made from pasteurised cow's milk and may contain added common salt. It contains not more than 44% moisture and its total solids content is not less than 50% milk fat.
Monterey Jack is commonly used as an interior melting cheese for quesadillas, California-style burritos, and some Mexican-style burritos. It can also be used on cheeseburgers or for grilled cheese sandwiches. It has a good melting quality for some pasta dishes.
Other ranchers in the area also produced the cheese, including Andrew Molera, whose Monterey Jack was especially well regarded. Dry Jack is a harder variety of the cheese, aged for up to 24 months.
