Why it works: Pepper and tomato are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Leg of Lamb, Larded
Ingredients
Directions
Prepare the lamb
Wash the lamb in cold water and dry it with a linen cloth.
Make deep incisions in the lamb and insert the pickled onions.
Season the lamb with salt and pepper, then dredge it with flour.
Brown and cook
Heat the butter and lard in a Dutch oven until hot.
Brown the lamb on both sides, adding hot water occasionally to baste.
Cover the Dutch oven to retain steam and cook the lamb slowly for one hour.
Make the gravy and serve
After cooking, add browned flour and hot water to the gravy.
Boil the gravy for five minutes, stirring well, then add tomato ketchup and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of lamb
- Forms the main body of the dish, and its fat and connective tissue provide the meat's flavour and moisture as it cooks.
- Flour
- Dredging coats the surface so it browns, and it thickens the gravy.
- Butter
- Fat for browning the lamb, adding richness and a nutty flavour.
- Lard
- Fat that conducts heat well for browning the lamb, adding savoury richness.
- Browned flour
- Adds a toasted, deeper colour and flavour to the gravy and helps it thicken.
- Tomato ketchup
- Adds sweetness and acidity to the finished gravy.
The step that matters
Brown the lamb on both sides. Browning creates flavourful Maillard compounds and a dark crust on the floured surface. Pale meat tastes flat, and crowding the pot or using too little fat causes steaming instead of browning.

Fit is the average pairing score against lamb, onion, pepper, flour, butter, ketchup. Candidates are from the same food group and used in at least 100 recipes.
