Maybe you got a ton of bananas you know you're not going to be able to eat before they go bad, or maybe you're lucky and have a store that sells food nearing its last Best Before date for half prize, and end up buying a lot of really ripe bananas.
What do you do with them? You freeze them, of course! They are great base for any smoothie, and many other things.
Its sounds pretty trivial though, right? If you want to freeze something, just throw it into the freezer, and you're done, right? Well, if you put whole bananas into your freezer, they will become rock hard and pretty hard to use in smoothies and other things, and if you didn't even peel it first, well... then you're going to have a hard time.
So the trick is to freeze them individually. Its pretty easy!
Step 1: Chop Your Banana(s)
Peel your bananas and chop it up into slices. In theory, the thinner the better, if you want it to be able to thaw easily, but if you got a lot of bananas, don't stress too much about it. Just make them about a cm thick or so.
Step 2: Bagging
This is the most important part. You could just throw all of them in a freezing bag and throw that into the freezer, but they will all stick together and freeze in solid lumps, and you have the same problem as if you just freezed the entire banana itself, and then you might as well not have bothered cutting them to begin with.
Get a big freezing bag and place each banana piece next to each other, sliced side facing up. Don't have any laying on top of one another, only side by side.
Once you're done, carefully slide the bag on top of a cutting board (or place it on a cutting board to begin with, if you aren't using said cutting board for chopping bananas, that is..) so they have something to rest on, once you put them into the freezer. Don't bother being able to close the bag just yet. The bag needs to be as flat as possible, for all the pieces not laying on top of one another.
My bag was a bit longer than the cutting board, so I carefully flipped the rest of it on top of the rest. You can fold the bag if necessary, just as long as the banana pieces aren't touching each other, and there is plastic in between those layers.
Step 3: Break Apart
It takes a few hours for them to freeze properly.
Once its done, you can take them out and break them from each other so they can be shook together in the bag, so you can close the bag. Put them bag into the freezer right away, as they thaw somewhat easily on the surface when they are exposed individually like that. Only a little thaw means they start sticking back together again.
