Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Boned Leg of Mutton Roasted
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the leg
Remove the bone from the leg of mutton, keeping the skin intact if possible.
Trim off most of the fat.
Fill the cavity with stuffing, adding the minced onion.
Sew the leg closed to prevent the stuffing from falling out. Bind and tie the leg securely.
Roast
Place it in a roasting pan and add 1 cup of hot water.
Roast in a 350°F (175°C) oven, basting occasionally.
Season with salt and pepper when partly cooked.
Once fully cooked, transfer the leg to a warm platter.
Make the gravy and serve
Skim the grease from the drippings, add 1 cup of water, and thicken with dissolved flour.
Serve the gravy in a gravy dish alongside currant jelly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the drippings into a smooth gravy as it cooks and dissolves.
- Onion
- Adds moisture and savoury aroma to the stuffing as it cooks inside the leg.
- Stuffing
- Fills the cavity, adding moisture and flavour to the meat as it roasts.
The step that matters
Sew and tie the leg securely before roasting. If the stuffing is not well enclosed, it can fall out and the leg may cook unevenly. Secure binding keeps the shape and holds the filling in place during roasting.
Swap the currant
How well each one fits the dish's main ingredients (mutton, onion, pepper, flour):

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