Understanding Cotija Cheese
Before discussing the freezing of Cotija cheese, it’s essential to understand its composition and characteristics. Cotija cheese is made from cow’s milk, although some variations might include a mix of cow and goat’s milk. The production process involves heating the milk, adding rennet to separate the curds from the whey, and then shaping the curds into their final form. The aging process can vary, resulting in different types of Cotija cheese, with the most common being fresh (or young) Cotija and aged Cotija. Fresh Cotija has a softer texture and a milder flavor, while aged Cotija is harder, crumblier, and has a sharper, more pronounced taste.
The Importance of Storage Conditions
The storage conditions of Cotija cheese play a significant role in its preservation. Adequate storage helps maintain the cheese’s quality and extends its shelf life.
