Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Milk and flour barely smell alike, yet cooks put them together in 78,219 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
- Sour milk
- Its acidity tenderizes the meat and gives the curry a tangy flavor.
- Flour
- Thickens the sour milk mixture so it clings to the meat as a sauce.
- Curry powder
- Provides the main spice flavor of the dish.
- Onion
- Adds savory sweetness and aroma as it cooks down into the curry.
- Lemon juice
- Adds acidity that brightens the flavor and helps tenderize the meat.
The step that matters
Cook for 45 minutes. Cooking for the full time lets the meat become tender and the flour thicken the sauce. Stopping early can leave meat tough and the sauce thin.
Swap the onion
How well each one fits the dish's main ingredients (mutton, lemon, pepper, milk, flour):
- Arrowrootfits better
- Spinachfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against mutton, lemon, pepper, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
