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 the onion softens.
Flour
Thickens the stock and cream into a smooth, binding sauce.
Egg yolk
Thickens the sauce as it cooks and adds richness and body.
Mushrooms
Add earthy savoury flavour and moisture to the filling.
Truffles
Add a concentrated, aromatic flavour to the filling.
Bread crumbs
Form a crisp, golden browned crust when fried.

The step that matters

Cool the filling before spreading. A warm, loose filling will soften the sweetbreads and make the coating slip off during dipping and frying. Letting it cool and thicken helps it hold its shape and stay in place.

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
