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

What each ingredient does

Butter
Browns and adds a rich, nutty flavour to the base of the sauce.
Flour
Thickens the stock into a smooth sauce as it cooks with the fat.
Stock
Forms the liquid base of the sauce, which thickens with the flour.
Cooked duck
Supplies the meat and savoury flavour that the sauce is built around.
Button mushrooms
Add earthy flavour and a tender, meaty texture to the sauce.
Lemon juice
Adds acidity that brightens the flavour of the rich sauce.

The step that matters

Stirring the flour into the browned butter and then the stock. Flour must cook in the fat long enough to lose its raw taste, and the stock must be added gradually while stirring so the sauce thickens smoothly without lumps.

Swap the onion
