Do you have a bunch of bananas sitting there on the verge of going bad? Just peel them, slice them and freeze the slices on a board. Once they are frozen, store them in a container or freezing bag in your freezer. Then the next time a hot day comes, take a bunch of slices out, toss them into a blender with a bit of honey and a tablespoon of yogurt (or double cream or mascarpone if you feel naughty), and blend the mixture until smooth. You will get a most delicious soft frozen yogurt! If you want a slightly firmer texture, prepare the mix before your dinner, serve it in individual cups and place them back into the freezer. By dessert time, the banana blend will feel ice-cream like. For a fancier version, mix it with frozen berries or stir at the last minute some chocolate sauce into ribbons... So delicious!
