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

What each ingredient does

Sweetbreads
Form the main body of the filling, giving it a soft, meaty texture once mashed.
Fine bread crumbs
Absorb liquid and help the mashed mixture hold together as a spreadable paste.
Melted butter
Adds richness and moisture, keeping the filling soft and smooth.
Thick sweet cream
Adds moisture and richness, helping the filling spread easily.

The step that matters

Heat the mixture slowly. Gentle heat keeps the mashed sweetbreads and cream from scorching or turning grainy, which would spoil the smooth, spreadable texture.

Swap the white pepper

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

  1. Tarragonfits better
  2. Nutmegfits better
  3. Garlicfits better
  4. White pepperthe original

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