I heard advice that you should store your condiments in there and fruits and veggies just go on the regular shelves. They may spoil a bit faster on the shelves, but you'll remember to use them.
I store a big bag of carrots in my crisper bc they keep so long and I always throw a couple in whatever I'm cooking, but leafy greens, broccoli, etc go on the shelves.
Soak a kitchen towel, wring it out, and line the bottom of the crisper with it. Feel it every once in a while to make sure it's still damp. That'll let your crisper be what it was designed to be: a little high-humidity box in an otherwise arid refrigerator.
Also, take note of how produce is stored at the grocery store. If the store doesn't refrigerate something (apples, tomatoes, avocados to name a couple), odds are you shouldn't either. The fruits and veggies that belong in the crisper are the ones that are periodically misted with water in the case at the store. Also probably don't keep anything tightly wrapped in plastic.
Diced onions and peppers freeze fantastically as long as you plan to use them in a sauce or soup. For some veg it’s also better to buy frozen if you’re not planning on eating it raw or cooking it immediately, like broccoli. Jesus Christ, never let broccoli rot. I’m pretty sure some corpses smell better.
Allegedly washing and drying veg also makes it last longer, but I always feel like if I made it that far I might as well just prep and store it.
Have you ever tried using an ozone generator in the refrigerator?
A colleague of mine said that vegetables stay fresh much longer, but I wasn't convinced.
it's a lot of hassle compared to just dropping a piece of dry ice in the veggie hospice.
Ozone is pollutant, you shouldn't inhale it or overconcentrate it -- hence it requires seals and sensors. While CO2 displaces the oxygen (the main cause of spoilage), is widely available and non toxic
