Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Crayfish-soup, with Rice
Ingredients
Directions
Prepare the crayfish
Boil the crayfish with wine, parsley, spices, and aromatics for 10 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Crayfish
- Provides the main flavour and meat that gives the soup its body and taste.
- Boiled rice
- Thickens the soup and adds body as it breaks down into the liquid.
- Tomato puree
- Adds acidity, colour and a deeper savoury flavour to the soup.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the finished soup.
- White wine
- Adds acidity and aroma while the crayfish cook.
The step that matters
Stir without boiling. Once the butter is added, boiling can cause the fat to separate and make the soup look greasy and broken. Gentle heat keeps the emulsion smooth and the flavour fresh.
Swap the tomato

Fit is the average pairing score against crayfish, white wine, parsley, rice, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
