Why it works: Coriander and pistachio share more aroma than cooks usually use. They rank in the top 7% of all ingredient pairs, and 78 recipes mention both. Both carry nonanal, which smells fat, citrus. The science ↓

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 dish as tender, slow-cooked meat.
- Eggs
- Whites are whisked and folded in to set and lighten the curry's texture.
- Butter
- Fat for frying the onions, carrying flavour and adding richness.
- Onions
- Softened by frying to build the base flavour and body of the gravy.
- Flour (in the method)
- Thickens the spice paste so it clings to the meat and gravy.
The step that matters
Adding the whisked egg whites. Egg whites set when heated, so they must be added to the meat and returned to heat gently; too much heat or stirring can make them curdle into uneven lumps.
Flavor stand-ins for the coriander

Fit is the average pairing score against mutton, egg, butter, onion, ginger, pistachio, nuts. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
