You may enjoy a good mystery but not likely the type that lurks in your refrigerator, hidden inside an opaque container until it decomposes beyond recognition. Store food in clear glass jars and you’ll see what you have on hand at a glance. This increases the likelihood that you’ll eat the food rather than stumbling upon an inedible puddle later and tossing it. (Store food in the freezer in jars also.)
Glass jars also work well for freezer storage and help reduce food waste. You can often find free jars at restaurants by simply asking. The staff would likely rather give them to you than recycle them or, worse, throw them out. Get free jars, reduce food waste and save money. Or repurpose your own glass jars! Win-win-win.
