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

What each ingredient does

Ripe tomatoes
Form the main sauce base, providing moisture, acidity and body once stewed and strained.
Sweetbreads
Provide the tender, delicate meat that is simmered in the tomato sauce.
Butter mixed with flour
Thickens the sauce and adds richness and a smooth, velvety texture.
Egg yolks
Enrich and thicken the sauce, adding richness and smoothness when added at the end.

The step that matters

Adding the beaten egg yolks. Egg yolks thicken when heated, so adding them just before serving and not letting the sauce boil keeps them smooth rather than scrambled or curdled.

Swap the tomato

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

  1. Chivefits better
  2. Shallotfits better
  3. Asparagusfits better
  4. Tomatothe original

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