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

What each ingredient does

Tomatoes
Form the liquid base, providing moisture and a mild acidity to the sauce.
Butter
Adds fat and richness, and carries flavor into the sauce.
Flour
Thickens the sauce as its starch swells when heated in the liquid.

The step that matters

Add the creamed mixture to the hot tomatoes. Flour starch swells and clumps when it meets hot liquid unevenly. Adding the butter and flour paste gradually while stirring helps it disperse and gives a smooth, evenly thickened sauce.

Swap the tomato

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

  1. Shallotfits better
  2. Carrotfits better
  3. Chivefits better
