Ethylene ripening bell

Ripen a hard avocado overnight by trapping a banana's ethylene under a bell

Ripe bananas give off ethylene, the gas that tells fruit to ripen. Under this bell it cannot escape. Put a hard avocado, pear, kiwi or peach on the lid with a ripe banana beside it, turn the bell over them and the fruit is ready in one or two days instead of a week. Flip it back over to store it. RIPEN is raised on the lid, which doubles as the plate.
