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.
