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

What each ingredient does

Milk
Forms the liquid base of the cream sauce that binds the mixture.
Flour
Thickens the milk into a cream sauce that gives the mixture body.
Egg yolks
Add richness and help bind the mixture so it holds its shape.
Sweetbreads
Provide the main meaty texture and flavor of the croquettes.
Mushrooms
Add moisture and earthy flavor to the filling.

The step that matters

Cooling the mixture before shaping. The sauce must cool and firm up so the cutlets keep their shape. If shaped while warm and soft, they can slump or break apart, and the coating may not stay on during frying.

Swap the onion

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

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

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