Description: Colby Jack or Cojack is a classic American combination of Colby and Monterey Jack cheese. The cheese was invented when Colby and Monterey Jack were blended together before pressing. A semi-soft cheese, it exhibits a unique eye-appealing marbled white and orange exterior that makes it a fun snack to eat on the go. The taste of Colby Jack varies from mild and smooth to lightly sweet to sharp and tangy. It groups well with deli meat, sandwiches, soups, sauces, burgers, dark bread like pumpernickel and rye, omelettes, casseroles, steamed vegetables, baked potatoes and fruits like apples and pears. Â Also, due to its good melting capabilities, it is the perfect choice for casseroles and nachos. This cheese is very popular with Mexican dishes.
