Why it works: Mutton and butter are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 3,781 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
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
Preheat your oven to 400°F (200°C).
Season the leg of mutton with coarse sea salt.
Roast and serve
Roast the mutton for 1 hour, or 1 hour and 15 minutes if the weather is frosty.
Baste the mutton with butter every 20 minutes.
Check for doneness before serving.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Mutton
- The main cut, whose fat and connective tissue soften and enrich the meat during a long roast.
- Butter
- Adds moisture and fat to the surface, helping it brown and stay tender as it roasts.
The step that matters
Check for doneness before serving. Roasting time varies with the size of the cut and the conditions, so timing alone can be unreliable. Checking the meat's doneness confirms it is cooked through and avoids serving it underdone or overdried.
