Preparation Finely chop all ingredients in batches in a food processor, transferring to a large bowl. Let stand at room temperature, loosely covered, 1 1/2 hours. Line a large sieve with layered cheesecloth squares and set over a large nonreactive pot. Carefully pour tomato mixture into center of cheesecloth, then gather up edges of cheesecloth to form a large sack and, working over sieve, squeeze solids to extract as much juice as possible. Discard solids. Chill juice until cold, about 1 hour, and stir before serving. (Juice will be pale in color but flavorful.)
