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

What each ingredient does

Butter
Enriches the onion base and carries flavour while it softens and browns lightly.
Flour
Thickens the cream and stock into a stable, spreadable sauce.
Egg yolk
Sets the thickened mixture as it heats, giving it a firmer, custard-like body.
Mushrooms
Add moisture and savoury depth to the filling.
Truffles
Contribute a strong aroma that defines the filling's flavour.
Bread crumbs
Form a crisp, golden browned crust when fried.

The step that matters

Fry in very hot fat until golden brown. Very hot fat seals the bread crumb coating quickly, so it browns and crisps before the creamy filling inside overheats or leaks out and the coating turns greasy.

Swap the onion

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

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

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