1/3 cup granulated sugar, or to taste
1/2 cup heavy cream
3 or 4 strawberries, puréed (may also be made with blueberries or other summer fruit)
Cut the lemons in half, squeeze out all the juice, and pour it into a large jug. Add the sugar, and whisk until it’s dissolved. Add 3 cups of cold water, and whisk again. Add the cream and puréed strawberries, and whisk until all the ingredients are combined. Pour over ice into 12-ounce glasses.
