What Kind of Cheese Is Monterey Jack?

Monterey Jack, sometimes known as Jack cheese is an American white, semi hard cheese made using cows milk.

Monterey Jack has a mild and slightly sweet flavour and was originally made in the 18th Century by Franciscan friars of Monterey California.

Monterey Jack cheese on it's own is a great topping for any family recipe and can be mixed with Colby cheese to create Colby-Jack or combined with yellow Cheddar to produce Cheddar Jack cheese. When mixed with chili peppers and herbs the cheese then becomes Pepper Jack.

Is Monterey Jack Cheese the Same as Mozzarella?

No. Monterey Jack is not a Mozzarella cheese. Mozzarella is a soft cheese, whereas Monterey Jack is a harder cheese. They both taste delicious and the harder cheese is still great for family meals and spaghetti dishes!
