Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the main body of the ragout; slow simmering softens its connective tissue for tenderness.
- Butter
- Adds richness and a rounded, savoury mouthfeel to the sauce.
- Onion
- Softens and sweetens during slow cooking, adding aroma to the stock.
- Stock
- Supplies the cooking liquid that becomes the moist, flavourful sauce.
The step that matters
Simmer very slowly and covered. A hard boil makes the meat tough and drives off liquid too fast. A covered, gentle simmer keeps the mutton tender and moist while its collagen slowly breaks down over the hour.
Swap the peas
How well each one fits the dish's main ingredients (mutton, butter, onion, pepper):
- Beansfits about as well
