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
Cut the meat off the bone of the rump and slice it across.
Dust the meat with flour.
Fry the thin part in butter until browned.
Stuff the thick end with suet, broiled chestnuts, anchovy, onion, and pepper.
Stew the stuffed beef in strong broth until tender.
Make the gravy and serve
Place the fried and stewed beef together on a dish.
Cut the fried beef in half and arrange it on each side of the stewed beef.
Strain the stewing gravy, add chopped pickled gherkins and broiled chestnuts.
Thicken the gravy with burnt butter and boil it two or three times.
Season the gravy with salt and pour it 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
- Rump of beef
- Provides the main meat, which is browned in part and stewed in part for contrasting textures.
- Flour
- Dusted on the meat to help it brown and to give the surface a light coating.
- Butter
- Fat used for frying the thin beef, adding browning and rich flavour.
- Suet
- Hard animal fat in the stuffing that adds richness and moisture to the thick end.
- Broiled chestnuts
- Starchy filling that adds body and a soft, mild sweetness to the stuffing and gravy.
- Burnt butter
- Browned butter that thickens the gravy and adds a nutty, toasted aroma.
The step that matters
Thicken the gravy with burnt butter and boil it two or three times. Burnt butter must be cooked to the right brown so it adds nutty flavour without bitterness, and the gravy needs to be brought to a boil to thicken and cook out raw taste.
