Colby-Jack is prepared from a blend of Colby and Monterey Jack cheeses. To begin, both cheeses are individually prepared by mixing pasteurized milk and bacterial cultures. Once fully mixed, a coagulant is added, which makes the cheese mixture thicken and take on a gel-like consistency; the addition of coagulant also serves to separate the cheese curds and whey.
