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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rump of beef
- Forms the main body of the dish and becomes tender through slow stewing.
- Suet
- Adds fat that keeps the stuffed filling moist and rich during cooking.
- Boiled chestnuts
- Add a soft, starchy texture to the stuffing and gravy.
- Butter
- Browns the floured beef when frying and enriches the gravy.
- Flour
- Browns the floured beef and thickens the gravy when rolled into butter.
- Onion
- Adds savoury depth and aroma to the stuffing.
The step that matters
Thicken the gravy with butter rolled in flour. Flour mixed with butter must be cooked into the hot liquid and brought to a boil, or the gravy stays pasty and floury-tasting instead of smoothly thickened.
Swap the lemon
How well each one fits the dish's main ingredients (beef, flour, butter, chestnut, anchovy, onion, pepper):

- Limefits about as well
- Cherryfits less well
Fit is the average pairing score against beef, flour, butter, chestnut, anchovy, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
