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

What each ingredient does

Sweetbreads
Main protein, which becomes tender and firm when blanched and braised, then browned by glazing.
Egg yolks
Bind the mashed potatoes and enrich them, helping the mixture set firm when poached.
Butter
Adds richness and moisture to the mashed potatoes and keeps the mold surfaces from sticking.
Mashed potatoes
Form the set, soft base of the chartreuse that holds the vegetables and sweetbreads together.
Broth
Provides moisture for braising, keeping the sweetbreads tender while they cook.
Tomato sauce
Adds acidity and savory depth to the cooking liquor for the finishing sauce.

The step that matters

Poaching the chartreuse in a bain-marie. The potato and egg yolk mixture sets as it heats. Gentle, even heat in a water bath keeps it smooth and firm; overheating can make the eggs curdle and the mixture grainy.

Swap the tomato

How well each one fits the dish's main ingredients (carrot, turnip, onion, potato, egg, butter, sauce):

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

Fit is the average pairing score against carrot, turnip, onion, potato, egg, butter, sauce. Candidates are from the same food group and used in at least 100 recipes.
