Why it works: Capers and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,550 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Boiled Leg of Mutton
Ingredients
Directions
Cook the mutton
Place the leg of mutton in boiling water with a little coarse sea salt.
Boil for two hours or more until tender.
Make the sauce
In a separate pan, melt ½ cup of butter.
Stir 1 tablespoon of flour into the melted butter until smooth.
Gradually add 1 pint of boiling water to the butter-flour mixture, stirring constantly.
Add 1 tablespoon of capers to the sauce and mix well.
Serve
Serve the mutton in a gravy dish, topped with the sauce, and garnish with boiled cauliflower and parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of mutton
- Is the main meat, becoming tender through long gentle boiling.
- Butter
- Enriches the sauce with fat and gives it a rich, smooth body.
- Flour
- Thickens the melted butter into a smooth base for the sauce.
- Capers
- Add a sharp, briny acidity that cuts the richness of the butter sauce.
The step that matters
Stir the flour into the butter and add the water gradually. Flour must be cooked briefly in fat before liquid is added, and the boiling water must be poured in slowly while stirring constantly. This prevents lumps and lets the starch thicken the sauce evenly and smoothly.
Swap the cauliflower
How well each one fits the dish's main ingredients (mutton, butter, flour, capers, parsley):
