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 ↓
Shrimp Soup
Ingredients
Directions
Prepare the shrimp
Pound the shrimps in a mortar with the lemon juice and butter until smooth.
Pass the mixture through a sieve.
Add pepper, salt, and nutmeg.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shrimps
- Provide the main flavour and body of the soup when pounded into a smooth pulp.
- Bread crumbs
- Soak up stock and thicken the puree, giving the soup body.
- Butter
- Adds richness and fat, carrying flavour and helping the soup feel smooth.
- Flour
- Thickens the butter and liquid into a roux that helps the soup thicken as it boils.
The step that matters
Stir until it thickens and boils. Flour needs to be stirred continuously while heating so it cooks evenly without lumps; boiling fully cooks the starch so the soup thickens properly.
Swap the lemon
How well each one fits the dish's main ingredients (shrimp, butter, pepper, nutmeg, bread, flour):
- Lemonthe original
- Avocadofits about as well
- Limefits about as well
- Coconutfits less well
Fit is the average pairing score against shrimp, butter, pepper, nutmeg, bread, flour. Candidates are from the same food group and used in at least 100 recipes.
