Bananas should be ripened on your counter, at room temperature.
Wrapping the stem in plastic wrap to keep them from ripening as quickly.
If they become overripe, peel them and slice into small chunks. Store these in a ZipLoc bag in the freezer (with a Sharpie, write the number of bananas stored in the bag).
These frozen bananas not only make great frozen treats but can be used in muffin recipes!
