Watermelon and Grapedfruit Agua Fresca

Ingredients

  • 10-lb watermelon
  • fresh grapefruit juice

Preparation

Step 1

Working in batches, puree 18 cups chopped seedless watermelon in a blender until smooth. Pour into a large bowl and let stand for 10 minutes. Skim the foam from the surface and discard. Set a fine-mesh sieve over a large picher; line the sieve with cheesecloth. Strain the puree into the pitcher (you should have almost 7 cups of juice).

Stir in 1 1/2 cups fresh ruby red grapefruit juice. Fill 8 glasses with ice. Divide agua fresca among glasses.
