You can use any frozen fruit you fancy for this although some may be more suitable than others. It does have to be frozen hard.
frozen fruit (I used strawberries and blueberries)
a dash of elderflower cordial or similar - lime cordial might be nice
a bit of honey or other sweetener if wanted
a few mint leaves
If you are using fresh fruit, it needs to go in the freezer several hours before so it is frozen solid. Cut any large fruit into smaller chunks.
Put the fruit, cordial, a couple of mint leaves and yogurt into a zizzer and blend until it is semi smooth and semi frozen, like a soft sorbet.
Taste and add something to sweeten, if wanted. I didn't.
Serve immediately, garnished with mint leaves Very delicious and refreshing.
