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

What each ingredient does

Sole
Provides the main body and flavor of the croquettes.
White sauce
Adds moisture and creaminess so the filling holds together softly.
Egg yolks
Bind the filling and set when heated, giving it structure.
Bread crumbs
Form a crisp, golden outer crust when fried.
Beaten egg
Helps the bread crumbs adhere to the shaped croquettes.

The step that matters

Stirring the mixture over low heat until the eggs are set. Egg yolks thicken and set when heated, but high heat or overcooking can scramble them and make the filling grainy. Gentle heat keeps it smooth and cohesive enough to shape.

Swap the onion

The recipe marks onion as optional. How well each one fits the dish's main ingredients (sauce, egg, nutmeg, pepper, bread, parsley):

  1. Shallotfits better
  2. Capsicumfits better
  3. Spinachfits better
  4. Onionthe original

Fit is the average pairing score against sauce, egg, nutmeg, pepper, bread, parsley. Candidates are from the same food group and used in at least 100 recipes.
