Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eschalots
- Provide the aromatic onion-like flavour that forms the base of the sauce.
- Mutton liquor
- Supplies the meaty liquid that the sauce is built on.
- Butter rolled in flour
- Thickens the sauce and gives it a smooth, rich body.
- Vinegar
- Adds acidity that brightens the sauce and balances the richness of the meat.
The step that matters
Add the butter rolled in flour and shake until it boils. Flour-coated butter must be dispersed and heated to the boil so the starch can gelatinise and thicken the sauce; otherwise it stays lumpy and floury.
Swap the lemon
The recipe marks lemon as optional. How well each one fits the dish's main ingredients (mutton, vinegar, pepper, walnut, butter, flour, parsley):
- Lemonthe original
- Limefits about as well
- Cherryfits less well
- Figfits less well
Fit is the average pairing score against mutton, vinegar, pepper, walnut, butter, flour, parsley. Candidates are from the same food group and used in at least 100 recipes.
