Put 300ml elderflower cordial and 300ml water in a saucepan. Shred a handful of mint (about 80g) finely with a knife, without crushing the leaves. Add the chopped mint to the cordial pan and stir in 100ml freshly squeezed lemon juice and 2 tbsp sugar. Heat the mixture until warm, but not hot, and leave to infuse for two hours.
Strain through a fine sieve into a freezer-proof container with a lid. Put on the lid and freeze for two hours. Remove from the freezer and break up the mixture- which should be partially frozen by now. repeat every one to two hours until the mixture is snow like.
Spoon into a low glass or teacup (I used large shot glasses and that works fantastically). Just make sure they are glass so you can see the beauty of it when you then dribble a teaspoon of cassis into the ice. Serve immediately!
If you want to make this dish even more impressive why not try making your own cassis?? There is a recipe for this on the great blog, The English Can Cook- www.marmitelover.blogspot.com
Oh yes we can.
