If you’ve got overripe bananas but no time to whip up a batch of banana bread, stick them directly in the freezer. No need to peel them and put them in a plastic bag. When you’re ready to bake, put the frozen bananas – which will have turned an ugly dark brown – on a plate to thaw. Once thawed, simply cut off one end of the banana and squeeze the fruit out of the skin. The texture will be a bit runny but it’s perfect for blending into a batch of bread. No waste, no plastic.
