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 ↓
Portugal Beef
Ingredients
Directions
Prepare the beef
Remove the bone from the rump of beef and cut it across.
Flour the beef and fry the thin part in butter.
Stuff the thick end with suet, boiled chestnuts, anchovy, onion, and pepper.
Stew and finish
Stew in a pan of good stock until tender.
Place the stewed part in a dish and cut the fried part in two, laying it on each side.
Strain the gravy, add chopped gherkins and boiled chestnuts, thicken with butter rolled in flour.
Add browning, boil, season with salt, and pour over the beef.
Garnish with lemon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef rump
- Forms the main body of the stew; slow stewing makes the meat tender.
- Flour
- Coats the beef for browning and thickens the gravy when rolled with butter.
- Butter
- Browns the thin beef pieces and, kneaded with flour, thickens the gravy richly.
- Suet
- Adds fat that keeps the stuffing moist and rich during stewing.
- Boiled chestnuts
- Give the stuffing and gravy a soft, starchy body and a mild sweetness.
- Onion
- Adds savoury aroma and sweetness to the stuffing.
The step that matters
Stew in a pan of good stock until tender. Beef rump is tough and needs long, gentle simmering so collagen breaks down into gelatin. Boiling hard toughens the meat and makes the gravy cloudy.

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.
