Our favorite drink this summer is watermelon lemonade. Thank you Smittenkitchen for the idea:

2 dl fresh-squeezed lemon juice
2 tablespoons sugar
4 dl  fresh watermelon puree without seeds
6 dl sparkling cold water

Stir lemon juice and sougar well together and add then the watermelon puree and the water. Serve over ice.
Garnish it with a thin watermelon or lemon wedge, if you’re feeling fancy.
