Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Boiled Mutton
Ingredients
Directions
Cook the mutton
Place the leg of mutton in boiling water and cook for 15 minutes per pound.
Reserve 1 cup of the cooking liquid.
Make the sauce
Cool the reserved liquid to remove the fat.
In a saucepan, heat the reserved liquid.
Stir in the butter and flour mixed with cold water and stir for 5 minutes.
Add the chopped parsley and bring the sauce to a boil.
Remove the sauce from heat and stir in the lemon juice.
Finish and serve
Lightly sprinkle the mutton with coarse sea salt as soon as it is removed from the fire.
Serve the sauce in a boat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton leg
- Provides the main meat, which becomes tender through long gentle simmering in water.
- Butter
- Adds richness and a smooth mouthfeel to the sauce.
- Flour
- Thickens the reserved cooking liquid into a smooth sauce.
- Lemon juice
- Adds acidity that brightens the rich, fatty sauce.
The step that matters
Cooling the reserved liquid to remove the fat. Fat from the cooking liquid floats and would make the sauce greasy and split. Chilling lets the fat solidify on top so it can be lifted off before reheating.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
