To drink, there was a crisp rosé and a refreshing concoction of fresh watermelon, lemon,
sugar and water known as "watermelonade." Apparently, it's one of the caterer's specialties, and everyone raved about the juicy, pink drink. 

Watermelonade

Serves 10

• 1/2cup sugar
• 4cups cubed watermelon
• 3 1/2cups water
• 1/2cup freshly squeezed lemon juice

1. Bring sugar and 1/2 cup water to a boil in a small saucepan, stirring sugar to dissolve. Set aside.
2. Put the cubed watermelon in a blender and puree until smooth, about 20 seconds. Strain through a fine mesh sieve. You should have about 2 cups of strained watermelon juice.
3. Mix the sugar syrup with 3 cups cold water and the lemon juice. Stir well.
4. Fill glasses with ice, add about 3 tablespoons of watermelon juice and then top off with lemonade. Stir gently before serving.
