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

What each ingredient does

Mushrooms
Provide the main body and earthy flavour of the sauce as they soften and release their liquid.
Butter
Carries the aroma and adds richness as the base for cooking the vegetables.
Flour
Thickens the sauce as it cooks briefly in the fat and then with the stock.
Stock
Supplies the liquid that becomes the sauce and carries its savoury flavour.
Meat extract
Adds concentrated savoury depth to the finished sauce.

The step that matters

Gradually add the stock, stirring constantly. Adding liquid slowly while stirring keeps the flour dispersed so it hydrates evenly, preventing lumps and giving a smooth, thickened sauce.

Swap the onion

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

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

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