Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Mutton, Breast of
Ingredients
Directions
Prepare the mutton
Cut the mutton into pieces about 2 inches square.
In a stewpan, heat a little fat or butter and fry the mutton until nicely browned.
Dredge the browned mutton in a little flour.
Stew
Slice the onions and add them with the herbs to the stewpan.
Pour in enough water to just cover the meat and simmer until tender.
Finish with peas
Remove the meat, strain the liquid, skim off the fat, and return the meat and gravy to the stewpan.
Add the green peas and boil gently until cooked.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the main meat, which becomes tender through long, gentle simmering.
- Flour
- Coats the browned meat and helps thicken the gravy as it cooks.
- Onions
- Add sweetness and savory depth to the gravy as they soften.
- Green peas
- Add sweetness and a fresh, tender texture at the end of cooking.
The step that matters
Simmer until tender. Mutton breast is a tough, fatty cut; it needs slow, gentle simmering in just enough liquid to break down its connective tissue. Boiling hard can toughen the meat and make the gravy cloudy.
Swap the peas
How well each one fits the dish's main ingredients (mutton, onion, pepper, flour, butter):
- Beansfits better
- Almondfits better
- Lentilsfits better
- Peasthe original
Fit is the average pairing score against mutton, onion, pepper, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
