Ingredients
- 1 oblong seedless watermelon (about 14 pounds)
- 3 cups seltzer
Directions
- Cut top third off watermelon; trim bottom just enough to make a flat surface. Scoop out flesh.
- Working in batches, puree watermelon in a food processor. Strain through a fine sieve; discard solids. (You should have about 9 cups juice.) Cover rind with plastic wrap. Refrigerate juice and rind until chilled, about 1 hour. Combine juice with seltzer; transfer to rind. via
