Press 12 ripe large Roma tomatoes to get 2 cups of Roma juice. Cover juice and place in refrigerator to cool.
Put all the remaining ingredients, 15 Roma tomatoes, onion, salt, pepper, sugar & garlic in the blender and puree until the juice is smooth. Pass the juice through a sieve to catch the seeds. Add the 2 cups of cold Roma juice to the Roma tomato blend. Serve in glasses that have been chilled in the freezer and garnish with a slice of lime.
