Pureed watermelon adds a summery twist to the classic Arnold Palmer combination of iced tea and lemonade. The sprightly thirst-quencher is also wonderful spiked with vodka.
Puree watermelon chunks in a blender until smooth. (You should have 4 cups.) Refrigerate in an airtight container up to 1 day ahead. When ready to serve, transfer to a pitcher; add lemonade-tea mixture. Stir to combine. Cut reserved rind into 1-inch wedges. To serve, fill glasses with ice; top with tea mixture. Garnish with watermelon wedges.
