Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 29,058 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓
Roast Leg of Mutton
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Let the leg of mutton rest for at least four days after killing.
Beat the leg to tenderize it.
Loosen the skin and marinate in oil, pepper, onion, and chopped parsley for 1-2 days.
Insert a clove of garlic into the knuckle.
Roast
Roast the leg in a 400°F (200°C) oven for about 1.5 hours, basting with the marinate and its own fat.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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 meat that becomes tender and juicy when roasted slowly.
- Oil
- Carries flavour from the marinade and helps keep the surface moist during roasting.
- Onion
- Adds aromatic flavour to the marinade that soaks into the meat.
- Chopped parsley
- Adds fresh, herbal aroma to the marinade.
- Garlic
- Adds pungent aroma that spreads through the meat as it roasts.
The step that matters
Basting with the marinade and its own fat. Regular basting keeps the surface moist and helps it brown evenly. Without it, the outer meat can dry out and harden before the centre is cooked through.
Swap the clove
How well each one fits the dish's main ingredients (mutton, pepper, onion, parsley, garlic):
- Thymefits better
