Cut up the tomatoes and put them, with the water, into a soup-pot. Add the celery, carrots, onion, green pepper, and cloves. Bring the soup to a boil, reduce the heat and add the salt & pepper to taste, and sugar. Simmer, partially covered, for 15 minutes. Remove from the heat and stir in the lemon juice. Strain, (Note: You can put the vegetables in the food processor and then sieve the juice out of the chopped veggies using the back of a wooden spoon). Correct the seasonings and serve either hot or cold.
