Why it works: Butter and capers are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 1,637 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Mutton and Lamb
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 the oven to 400°F (200°C).
Place the leg of mutton or lamb in a pan.
Season thoroughly with coarse sea salt.
Cook
Bake for 12 minutes per pound of lamb or 15 minutes per pound of mutton.
For boiling, plunge the mutton into boiling water.
Scald for 15 minutes per pound, and add 30 minutes in cold weather.
Serve
Serve with drawn butter and nasturtiums or capers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of mutton or lamb
- Main protein that becomes tender and juicy as it cooks through.
- Coarse sea salt
- Seasons the meat thoroughly and flavors the outer surface.
- Butter
- Adds fat and richness, and makes the serving sauce smooth and savory.
- Nasturtiums or capers
- Adds sharp, acidic bite that cuts through the richness of the meat and butter.
The step that matters
Cooking time per pound. Time depends on the weight and type of meat, because heat must travel to the center of a thick cut. Mutton is given more time per pound than lamb, so underestimating the weight or time can leave the center undercooked.
Swap the capers
How well each one fits the dish's main ingredients (mutton, butter):
- Pepperfits better
- Parsleyfits about as well
- Capersthe original
- Thymefits about as well
Fit is the average pairing score against mutton, butter. Candidates are from the same food group and used in at least 100 recipes.
