Step 1

Pick the leaves from the mint and put in the base of a large jug. Sprinkle over the sugar, then pour over the lime juice. Use the end of a rolling pin or wooden spoon to muddle everything together, crushing the mint leaves and dissolving the sugar.

Step 2

Add some ice, then pour over the chilled soda water. Taste – you may like it a little sweeter, if so add pinches of extra sugar. Extra lime wedges (and ice) can be added to glasses for serving, or straight into the jug too.
