Why it works: Onion and celery are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 18,518 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Baked Leg of Mutton
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).
Stuff and lard
Stuff the leg of mutton with the rich forcemeat.
Lard the top and sides of the mutton with bacon.
Braise and serve
Place the mutton in a pan with water, chopped onion, and chopped celery.
Add red wine, mushroom ketchup, and curry powder to the pan.
Bake until cooked through, then serve with the gravy.
Garnish with fried forcemeat balls.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the main meat, which becomes tender and flavorful as it cooks slowly.
- Bacon
- Melts fat into the meat as it bakes, keeping the lean mutton moist and adding savoriness.
- Red wine
- Adds acidity and depth to the liquid, helping build the gravy's flavor.
- Mushroom ketchup
- Adds concentrated savory, umami flavor to the cooking liquid and gravy.
- Rich forcemeat
- Fills the cavity with a moist, savory stuffing that flavors the meat from inside.
The step that matters
Bake until cooked through. Mutton must reach a safe internal temperature throughout, and a thick leg can look done outside while the center is still underdone. Checking the thickest part with a thermometer prevents this, and covering the pan with liquid helps the meat stay moist during the long bake.
