I think it’s safe to say that at some point or another, we’ve all been faced with spotty bananas that we knew we just weren’t going to get to before they turned that final corner into banana heaven (the compost pile). Not due to lack of ideas, but due to lack of time. Luckily, there’s a quick and easy way to extend the life of your ripe bananas.
First, peel the bananas and lay them on a parchment-lined baking sheet. Put the sheet in the freezer for two or three hours, until the bananas are solid. This is called flash freezing. It will enable you to pull one banana at a time out of the freezer. If you just put them all together in a bag they would freeze in one giant banana lump.
Peel them off the parchment and place them in a freezer safe zip-top bag. Use them within a month (I date mine on the bag because I have a really bad concept of time). To use them for banana bread or anything calling for pureed banana, just let the banana sit out until soft and smoosh it with a fork.
