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

What each ingredient does

Ripe tomatoes
Provide the main body and sweet, acidic flavor of the sauce.
Sweet cream
Adds richness and a smooth, creamy texture to the sauce.
Flour
Thickens the liquid so the sauce coats the toast rather than running off.
Butter
Adds fat and flavor to the sauce and enriches the buttered toast.

The step that matters

Scalding without boiling. Once the cream and flour go in, boiling can curdle the cream and cause the flour to clump or taste raw. Heating just until steaming hot keeps the sauce smooth, and removing it from heat right away prevents it from reducing or breaking.

Swap the tomato

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

  1. Leekfits better
  2. Spinachfits better
  3. Shallotfits better
  4. Tomatothe original

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