Spoil No More: Avocados
Case #2: Browning Avocados
Avocados make for great party guacamole, but nobody wants to dip their chips in a bowl full of browned mush. Avocados turn brown when they contact oxygen. So, simple solution: don't let air near your avocados. Many try to do this with plastic wrap or sealed containers. But let's face it — that never works very well. (Plus, we don't like plastic!) Instead, put the cut avocado in a bowl on top of some onion slices. It'll slow down the browning process with magical onion powers — just kidding, onions aren't magic. But they do have sulfur, which may explain how they preserve the avocados.
