Expiration & Storage Tips
When does cotija cheese expire?
Packaged cotija cheese typically comes with a 'best by' or 'use by' date printed on its packaging, which is usually about 6 months from its production day given it's still sealed. Once you've opened the package, the cheese should stay fresh for about 2 to 3 weeks if stored properly. However, if you've bought fresh cotija cheese from a cheese counter, you should consume it within 1 to 2 weeks. When it comes to freezing, cotija cheese can be frozen to extend its shelf life by additional 6-8 months, but keep in mind it might alter its texture, making it slightly more crumbly than usual.
How do you tell if cotija cheese is bad?
Cotija cheese gone bad will exhibit a few noticeable signs. First, if there is visible mold that isn't a part of the cheese itself, it's time to toss it. Secondly, if the cheese develops a strange or sour smell, quite different from its original salty aroma, it's a sign of spoilage. Lastly, if the cheese has either a too-hard or too-soft texture, or if it's discolored, it's likely that the cheese is no longer safe to consume.
Tips for storing cotija cheese to extend shelf life
• Always store cotija cheese in the refrigerator to maintain its freshness. Ideally, keep it in the vegetable drawer where humidity levels are more stable.• After opening, wrap the cheese in wax or parchment paper before placing it in a loose-fitting food storage bag or a small container. Avoid using cling wrap, as it can promote the growth of bacteria.• If you want to freeze cotija cheese for longer-term storage, grate it first and then store it in a freezer-friendly bag. Be sure to press out as much air as possible from the bag before sealing. To use it after freezing, there is no need to thaw it. It can be added directly to your hot dishes.
