Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eschalots
- Provide the main aromatic flavour as they soften in the hot liquor.
- Mutton liquor
- Forms the savoury liquid base that carries the flavours of the sauce.
- Butter rolled in flour
- Flour thickens the liquid as it boils, and the butter adds richness and body.
The step that matters
Stir in the butter rolled in flour until it boils. Flour needs to be heated while stirred to thicken the liquid smoothly. If it is added without stirring or not brought to a boil, it can clump and leave the sauce floury and thin.
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.
