You will need:
- 300g (10oz) blueberries, fresh or frozen
- Juice of 1 lemon
- 1-2 tablespoons agave syrup or honey
- Vanilla ice cream, to serve
- Champagne, to serve (optional)
Put the fresh or frozen blueberries, whichever you are using, the lemon juice and the agave syrup or honey, whichever you’re using, in a liquidiser and whizz until fine. Then push the mixture through a sieve and serve over vanilla ice cream, or pour a teaspoon or two into the bottom of a glass of bubbly!
