Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, and carries the flavour of the aromatics.
- Flour
- Thickens the liquid into a smooth sauce as it cooks.
- White wine
- Adds acidity and aroma that brighten the sauce.
- Mushrooms
- Add earthy savoury flavour and body to the sauce.
- Onion
- Builds sweetness and savoury depth as it softens in the butter.
The step that matters
Stirring in the flour. Flour added to hot fat must be stirred well so it cooks evenly; otherwise lumps form and the sauce tastes raw and floury.
Swap the onion
How well each one fits the dish's main ingredients (butter, mushroom, parsley, laurel, flour, white wine, pepper):
- Shallotfits better
- Carrotfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against butter, mushroom, parsley, laurel, flour, white wine, pepper. Candidates are from the same food group and used in at least 100 recipes.
