Keeping Velveeta cheese fresh and long-lasting requires careful storage. To get the most out of your Velveeta cheese, start by keeping it chilled in the refrigerator at 40°F or below. For maximum longevity, store your Velveeta cheese in an airtight container and place it as far away from other items with strong odors as physically possible to avoid any potential contamination or cross-contamination of flavors. Additionally, wrap the receptacle containing your Velveeta securely with plastic wrap for extra protection against stinky fridge neighbors!
In terms of timeframes, unopened packages stored correctly can last anywhere from 1 to 3 months past their printed expiration date. If you plan on using them before this time frame is up, check that they feel cool to the touch and smell mild; if they're hard or smell strongly acidic or pungent then discard them right away. Once opened you'll need to consume it within 3 days if refrigerated - just make sure to keep leftovers properly sealed between servings!
