Why it works: Parsley and lime match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 547 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Indian Curry Sauce
Ingredients
Directions
Make the roux
Melt the butter in a stewpan.
Add the chopped onion, sliced mutton, and parsley. Stir over low heat for 5 minutes.
Add the flour and curry powder. Fry for a few minutes to cook the flour.
Simmer and strain
Stir in the broth and lime juice.
Allow to simmer for 30 minutes, stirring occasionally.
Strain the sauce through a fine strainer or tammy cloth back into the stewpan.
Bind and finish
Bring to a boil and bind with the egg yolk, cream, and butter.
Stir over the heat for a few seconds, but do not let it boil again.

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
- Flour
- Thickens the sauce when cooked in butter, giving it body.
- Egg yolk
- Binds and enriches the sauce, giving it a smooth, velvety texture.
- Butter
- Carries the curry flavour and adds richness to the sauce.
- Curry powder
- Provides the main spiced flavour of the sauce.
- Broth
- Forms the liquid base of the sauce.
The step that matters
Do not let the sauce boil after adding the egg yolk. Boiling after the yolk is added can curdle the egg proteins, making the sauce grainy and thin. Heat it gently only until it thickens.
Swap the lime

- Avocadofits about as well
Fit is the average pairing score against butter, onion, mutton, parsley, flour, veal, egg. Candidates are from the same food group and used in at least 100 recipes.
