Why it works: Mutton and pork match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and 1,237 recipes mention both. Both carry 1-nonanal, which smells fatty, waxy. The science ↓
The recipe
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Make deep slits in the leg of mutton and insert strips of salt pork.
Roll the mutton in coarse sea salt, black pepper, and ground cloves.
Roast and glaze
Bake for two hours, basting frequently.
About one hour before serving, spread currant jelly over the mutton. Return to the oven and let it brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of mutton
- Forms the main body of the dish and carries the flavour of the roast.
- Salt pork
- Adds fat and savoury flavour that melts into the meat as it roasts.
- Currant jelly
- Its sugars caramelise in the oven, giving the surface a glossy, browned finish.
The step that matters
Spreading the currant jelly. Jelly contains sugar that burns easily, so it should go on late, about an hour before serving, and the oven heat should be watched while it browns.
Flavor stand-ins for the currant

Fit is the average pairing score against mutton, pork, pepper, clove. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
