Starving-Student - Onion Tomato Soup

4 tablespoons of butter
1 small, or 1/2 of a medium-sized onion, chopped
1/2 cup of thinly sliced celery
1/2 cup of flour
4 cups of tomato juice
Water
Sugar
Salt
Crushed red pepper flakes
Milk

Melt the butter in a Dutch oven or large soup pot.

Add the onion and the celery. Saute until the onion is tender.

Slowly, stir in the flour. Cook, stirring almost constantly, until the flour is slightly browned.

Slowly, add the tomato juice, stirring as you add.

Stir the mixture until it is smooth with no lumps and it is the thickness of gravy.

Add a little water to thin slightly. Add the sugar, the salt, and the red pepper flakes all to taste.

Heat the soup to almost the boil and then add some milk to make it the desired consistency.
