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 ↓
Boiled Leg of Mutton
Ingredients
Directions
Prepare
Wash the leg of mutton clean and trim the shank bone and knuckle.
Place the mutton in a pot and cover it with water.
Boil
Boil gently for 2 to 3 hours, skimming the surface regularly.
If using the broth for soup, add a little salt while boiling; otherwise, salt the meat when partially cooked.
Remove from heat and cover the pot to let it steam for 10 to 15 minutes.
Serve
Serve with melted butter mixed with capers or nasturtiums.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton leg
- Provides the meat that becomes tender through long, gentle simmering.
- Melted butter
- Adds richness and moisture to the served meat.
- Capers or nasturtiums
- Add a sharp, tangy flavour that balances the rich meat and butter.
The step that matters
Boil gently for 2 to 3 hours. A rolling boil toughens meat proteins and makes the surface cloudy, while a gentle simmer lets connective tissue break down slowly into tender meat. Skimming removes foam that would otherwise cloud the broth.
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.
