We seem to be having some problems with keeping bananas for any length of time. Our house is a bit of a glasshouse and so the tell-tale twinges of brown are appearing on the skins of bananas a little quickly. In the search for something to do with them, I discovered frozen banana.
It's simple - Freeze banana coins (I missed out on this instruction, meaning I had some issues with the puree stage...). Puree banana coins.
That's it. I gather you can refreeze it but it was quite tasty as it was and both D and I polished it off within minutes. I'm going to try and play with the recipe a little - adding cinnamon is my next choice.
