Cut the tomatoes, scallions, cucumber, and onion in large pieces and place them in a food processor fitted with the steel blade. Add the garlic and pulse until the soup is coarsely pureed. Place it in a large bowl and whisk in the vinegar, olive oil, celery salt, red pepper flakes, tomato paste, tomato juice, 1 tablespoon salt, and 1 1/2 teaspoons pepper. Cover with plastic wrap and chill for 4 hours or overnight. |
