Tomato Sauce I

Ingredients

Directions

  1. Cook onion with tomatoes for fifteen minutes.

  2. Rub the mixture through a strainer.

  3. Add the strained tomatoes to butter and flour (seasoned with salt and pepper) and cook together.

  4. If tomatoes are very acidic, add a few grains of soda.

  5. If you want to retain the red color, brown the butter and flour together before adding the tomatoes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Tomatoes
Provide the main body, flavor and liquid of the sauce.
Butter
Adds richness and fat, and combines with flour to form the base of the sauce.
Flour
Thickens the sauce when cooked with butter into a roux.

The step that matters

Cooking the butter and flour together before adding the tomatoes. Cooking flour in fat builds a roux that thickens the sauce evenly. Adding the tomatoes too early or without cooking the roux can leave lumps and a raw floury taste.

Swap the tomato

How well each one fits the dish's main ingredients (onion, butter, flour, pepper):

  1. Chivefits better
  2. Okrafits better
  3. Leekfits better
  4. Tomatothe original

Fit is the average pairing score against onion, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
