Do you actually know how to set the crisper or humidity drawers in your fridge? Or do you just bump the notches towards the middle as a safety precaution?
As to the contents of those drawers, perhaps you fill them haphazardly: all greens in one drawer, fruits in the other, everything else where there's room. Sounds good enough, until some things seem to go bad faster than others! It's high time you learn how to use these refrigerator drawers properly... for the fruits and veggies' sake!
