I love avocados. Absolutely love them. However, I'm finding that now that I'm eating smaller portions, I only want to eat about half of one at a time. The problem is that I live alone and I'm cooking for one, so I have to store the other half. And even if I try to use it the next day, I always find that it's brown and gross by the time I come back to it, and I end up having to throw it away.
Has anyone found a secret for keeping half an avocado from going bad after a day or two?
