Monterey Jack is an American cheese made from cow's milk. It originates from Monterey in California, where it was first made by Spanish missionaries under the name queso blanco pais, but it was later taken from them by David Jack, who bought nearly all of Monterey in 1859 and renamed the cheese to Jack's Cheese, soon to be called Monterey Jack's Cheese.
Historical shenanigans aside, this semi-hard cheese has a firm, open, supple, and compact texture and a natural rind. It is pale yellow in color, while the flavors are mild and buttery. Monterey Jack also melts exceptionally well. It has a few subvarieties, such as Dry Jack and Pepper Jack.
