Slice half of a large melon, discarding the rind and seeds. Cube up 5 ⅔ cups of melon (1.1 kg) and spread it out in a single layer on a large cookie sheet. Freeze for at least 1-2 hours, but preferably overnight.
02 -
Place some of the frozen watermelon along with the freshly squeezed lime juice and the sugar in a powerful blender. Blend on low speed until combined.
03 -
Gradually blend in the remaining melon and the frozen strawberries. You'll need to add water occasionally to help the blender crush the fruit.
04 -
Taste the drink and add more sugar or lime juice if desired. Adjustments may be needed depending on the sweetness of the fruit used.
05 -
Pour into 14-ounce glasses and garnish with a small watermelon slice on the rim of the glass and paper straws. Serve immediately, or pour into a pitcher and store in the freezer until ready to serve.
