Notes
Storage: To slow the ripening process of bananas, store them away from heat and direct sunlight and wrap banana stems tightly in plastic wrap (the ethylene gas is released through the banana stem, so you can reduce what is released if you wrap the stems). You can also transfer them to the fridge when they are at peak ripeness.
