Here are some instructions for storing cherries to maximise their lifespan — assuming you can stop yourself from eating them all as soon as you get them home!
When selecting cherries at the store, look for shiny, firm fruits with green stems attached. Green stems are a freshness indicator. Avoid choosing soft cherries with major bruises or blemishes.
Store cherries unwashed and uncovered in the coldest part of the refrigerator.
Avoid storing cherries near strong-smelling foods (like onions or garlic). Your cherries can take on the odor of these foods which alters their taste.
Rinse cherries under cold water only when you are ready to use or eat them.
Avoid placing cherries near windows, sunlit areas or other warm areas for a prolonged period of time. Warm environments cause cherries to deteriorate quickly.
Periodically check your cherries for decay. Remove rotten cherries immediately in order to preserve the rest of your bag.
