Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Breast of Mutton and Green Peas
Ingredients
Directions
Prepare and brown
Cut the breast of mutton into small pieces and dredge with flour.
Fry in butter until nicely browned.
Stew and finish
Cover with water, add pepper and salt, and stew over moderate heat until the meat is very tender.
Remove the meat and skim off the fat from the gravy.
Add the boiled peas to the strained gravy and let it boil gently until the peas are done.

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
- Breast of mutton
- Provides the main meat, which becomes tender through slow stewing.
- Flour
- Coats the meat, helping it brown and thickening the gravy.
- Butter
- Carries the frying heat and adds richness and browning to the meat.
- Tender young peas
- Add sweetness, soft texture and fresh flavour to the gravy.
The step that matters
Stewing the mutton over moderate heat. Collagen in mutton breaks down slowly into gelatin at gentle heat, making the meat tender. Boiling hard toughens the muscle fibres and can leave the meat stringy.
Swap the peas
How well each one fits the dish's main ingredients (mutton, flour, butter, pepper):
- Almondfits better
- Beansfits better
- Walnutfits about as well
- Peasthe original
Fit is the average pairing score against mutton, flour, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
