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 ↓

Directions
Prepare
Cut very thin slices from the leg or loin of mutton.
Sprinkle the slices with salt, pepper, pounded mace, minced savory herbs, and minced shallots.

Simmer gently for 6 to 7 minutes and serve immediately.

Butter and flour 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
- Mutton
- Provides the main meat, which is cooked briefly to stay tender and juicy.
- Butter
- Fat that browns the slices and adds rich flavour.
- Flour
- Thickens the gravy so it coats the slices.
- Gravy
- Liquid that moistens the meat and forms the sauce.
- Lemon juice
- Adds acidity that brightens the rich meat and gravy.
- Shallots
- Add a mild, sweet onion-like aroma to the meat.
The step that matters
Fry the slices in butter until browned. Browning the thin slices over fairly high heat builds savoury flavour through the Maillard reaction. Crowding the pan or stopping too early leaves the meat grey and bland.
Swap the mace
How well each one fits the dish's main ingredients (mutton, pepper, shallot, butter, flour, lemon):
- Parsleyfits better
- Capersfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against mutton, pepper, shallot, butter, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
