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

What each ingredient does

Sweetbreads
Provide the main substance, becoming tender and delicate after parboiling and simmering.
Butter
Enriches the sauce and carries flavour while the flour is cooked into a roux.
All-purpose flour
Thickens the milk into a smooth sauce as its starch swells with heat.
Milk
Forms the body of the sauce, which thickens as it heats and coats the sweetbreads.
Mushrooms
Add earthy flavour and moisture to the casserole.

The step that matters

Gradually stir in the milk and cook until the sauce thickens smoothly. Adding milk slowly while stirring lets the flour starch disperse evenly before it swells. Adding it all at once can create lumps that are hard to smooth out.

Swap the white pepper

How well each one fits the dish's main ingredients (butter, flour, mace, lemon, milk, mushroom):

  1. Nutmegfits better
  2. Thymefits better
  3. Marjoramfits better
  4. White pepperthe original

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