Tomato Sauce No. 1

Process: Cook tomatoes and slice of onion fifteen minutes, rub through a strainer. Melt butter in a sauce-pan, brown it richly, add flour and when well browned add seasoning and tomato pulp. A few grains of soda may be added if tomatoes are too acid. Stir until sauce is smooth and reaches the boiling point, then pour over Breaded Tongue.
