How to Store an Avocado
If you want to keep a cut avocado for use later, try storing it in a tightly lidded container with a piece of onion. No longer will you have to waste a perfectly good half of an avocado just because it's starting to brown. Cut the onion and place the cut side against the cut side of the avocado the sulphur in the onion will keep the avocado from reacting and turning brown and slimy. The avocado can be stored this way for 1 or 2 days. It's that easy and it really works!
