How do I know if a black banana is too old to be eaten?
From time to buy, I buy too many bananas. For the future, I am considering refrigerating them instead of eating them, but they turn black.
How can I know whether a black banana is still edible?
if you can catch them when they're very ripe, I suggest a quick peel, plasticwear, and plop in freezer before they're totally gone. Then you can use at your leisure for shakes and smoothies.
