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 ↓

Directions
Prepare
Cut and prepare the fillet of mutton.
Flour and brown it in a little butter.

Butter and flour 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 fillet (in the method)
- Provides the meat that becomes tender during slow stewing.
- Flour
- Coats the meat so it browns and helps thicken the gravy.
- Gravy
- Supplies the liquid that keeps the meat moist during long cooking.
- Onions
- Add sweetness and savory depth as they soften in the stew.
The step that matters
Stew slowly for 3.5 hours. Low, gentle heat over a long time breaks down the connective tissue in mutton, making it tender. Boiling hard would toughen the meat and cloud the gravy.
Swap the onion
How well each one fits the dish's main ingredients (pepper, butter, flour):
- Shallotfits better
- Chivefits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
