Why it works: Onion and carrot are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 21,601 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Braised 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 the meat
Remove the bone from the leg of mutton up to the first joint.
Roll strips of bacon in mixed spice and savoury herbs, and lay them inside the boned portion. Alternatively, fill the cavity with highly seasoned forcemeat.
Braise
Place the meat in a large pot with bacon slices underneath and on top.
Add onions, carrots, bay leaves, savoury herbs, bones, and gravy.
Stew the meat gently for 4 to 5 hours, keeping embers on top. Alternatively, place the pot in a 350°F (175°C) oven.
Glaze and serve
Strain the gravy.
Reduce the strained gravy to a glaze.
Brush the glaze over the meat.
Serve with boiled white beans or a mild ragout of garlic or eschalots underneath.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of mutton
- Provides the main meat, which becomes tender through long, slow braising.
- Bacon
- Adds fat and savoury flavour that bastes the meat as it cooks.
- Onions
- Build savoury sweetness and body into the braising liquid.
- Carrots
- Add sweetness and aroma to the braising liquid.
- Gravy
- Forms the braising liquid that keeps the meat moist during long cooking.
The step that matters
Stewing the meat gently. Long, gentle heat lets the connective tissue in the mutton break down slowly; a hard boil would toughen the surface and dry the meat before it becomes tender.
