Goal: Slow a bunch of bananas from ripening to quickly.
After bringing a bunch of bananas home from the grocery store, seperate the bunch into individual bananas and place in different areas of the kitchen. This prevents the ethylene gas emitting from each banana from ripining the other bananas on the bunch to quickly.
Wrap bananas in plastic bags and store in cool place.
