Tomato Sauce l (without stock)

Ingredients

1/2 can tomatoes or 1 & 3/4 cups fresh stewed tomatoes
1 slice onion
3 tbsp butter
3 tbsp flour
1/4 teaspoon salt
1/8 teaspoon pepper

Directions

Cook onion with tomatoes fifteen minutes, rub through a strainer, and add to butter and flour (to which seasonings have been added) cooked together. If tomatoes are very acid, add a few grains of soda. If tomatoes are to retain their red color it is necessary to brown butter and flour together before adding the tomatoes.
