Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Ingredients
Directions
Prepare
Cut the mutton into small pieces.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tinned roast mutton
- Provides the main meat, which is cut small and heated through in the sauce.
- Butter
- Fat that browns the mutton, adding richness and savoury flavour.
- Flour
- Thickens the gravy into a smooth, coating sauce.
- Gravy
- Forms the liquid base of the sauce, adding moisture and meaty flavour.
- Shallots
- Add a mild, sweet onion-like aroma as they cook with the meat.
The step that matters
Thickening the gravy with flour. Flour must be cooked into the hot gravy, or it can form lumps and leave a raw, pasty taste. Letting the sauce boil briefly lets the starch swell and thicken evenly before the mutton is added.
Swap the mace
How well each one fits the dish's main ingredients (mutton, flour, sauce, shallot, butter, pepper, lemon):
- Capersfits better
- Parsleyfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against mutton, flour, sauce, shallot, butter, pepper, lemon. Candidates are from the same food group and used in at least 100 recipes.
