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

What each ingredient does

Sweetbreads
Provide the tender, delicate meat that forms the main body of the dish.
Eggs
Thicken the cream and stock mixture into a smooth, custard-like sauce when gently heated.
Cream
Adds richness and fat, giving the sauce a smooth, silky mouthfeel.
Butter
Adds fat and flavour, and with flour helps thicken the sauce.
Flour
Thickens the sauce when cooked with butter, giving body and preventing it from being thin.
Fresh onions
Contribute savoury, aromatic sweetness to the stock as it simmers.

The step that matters

Add the egg and cream mixture without overheating. Eggs thicken by gentle heat; if the mixture boils or is added too hot, the eggs scramble and the sauce becomes lumpy. Adding it off the boil and stirring steadily keeps it smooth.

Swap the mace

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

  1. Nutmegfits better
  2. Capersfits better
  3. Tarragonfits better
  4. Macethe original

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