Gin & tonic with watermelon and cucumber

Serves six to eight

• 0 White wine
• 2 unwaxed lemons
• 200g elderflower cordial
• 1 bottle chilled sauvignon blanc
• 750g sparkling water
• 1 lime slice
• 0.5 small watermelon
• 50g summery gin
• 150g Double Dutch cucumber
• 1 strip cucumber

Step 1
Gently wash the lemons, then rub them with the back of a knife to release the oils.

Step 2
Cut them in half and put them in a 1.5-litre jug with the cordial and the wine, then refrigerate until you’re ready to drink.

Step 3
Add ice and the water, stir and serve garnished with a slice of lime or a sprig of borage.

Step 4
Peel and deseed the watermelon, then cut the flesh into 2.5cm cubes.

Step 5
Place these on a baking sheet lined with greaseproof paper, cover with cling-film and freeze for at least four hours.

Step 6
Once they’re frozen, the watermelon ice cubes will keep in a tub in the freezer for a month.

Step 7
Put five or six watermelon ice cubes into a highball or goblet-shaped glass, add the gin and top with tonic, to taste.

Step 8
Use a vegetable peeler to cut a thin strip of cucumber and curl it into the glass as a garnish.
