Step 1

Place raspberries, lime, mint and sweetener (if using) into a glass.

Step 2

Muddle together for about 1 minute to release the juice from the lime and raspberries, and the flavour from the mint. If you don’t have a muddler, the back of a wooden spoon or a soup spoon works well.

Step 3

Top with sparkling water and stir gently.

Step 4

Add ice and garnish.
