watermelon lemonade drink

• 1 large or 2 small watermelons
• 250ml lemon juice (from a bottle or squeeze your own)
• 100g golden caster sugar
• 1l bottle soda water
• 1 lime, cut into slices
• small handful mint
• crushed ice

Method

1. Cut the top off the watermelon and hollow it out using a large spoon, fishing out any pips along the way. Mash the flesh through a sieve into a bowl. Put the flesh in a blender (or use a tall jug and hand blender) with the lemon juice and sugar, whizz to a purée, then stir in the soda.
2. Heap some ice into the hollowed-out watermelon and fill it with the lemonade mixture. Serve the rest in a jug with the lime slices and mint. Have a bowl of extra crushed ice on the side so people can help themselves.
