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 base
Boil shrimp shells in 1 cup of water with lemon juice.
Pound the shelled shrimp with butter until smooth.
Soak the penny roll in some cold fish stock, then pound it with the shrimp.
Combine the shrimp paste with the remaining fish stock in a saucepan.
Strain the boiled shells and add the liquid to the soup.
Season and finish
Season with nutmeg, cayenne, and salt.
Just before serving, remove from heat and stir in the beaten egg yolks and cream. Do not let it boil.
Serve with small round croutons made from fried bread.

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 the body of the soup once pounded smooth.
- Butter
- Adds richness and a smooth, silky mouthfeel to the pounded shrimp.
- Penny roll
- Soaked and pounded in, it thickens the soup and helps bind the shrimp paste.
- Egg yolks
- Thicken the soup gently and add richness when stirred in off the heat.
- Cream
- Adds richness and a smooth texture to the finished soup.
The step that matters
Adding the egg yolks and cream. Egg yolks thicken by setting when heated. If the soup boils after they go in, they can curdle and turn grainy, so they must be stirred in just before serving, off the heat.
Swap the nutmeg
How well each one fits the dish's main ingredients (fish, shrimp, butter, egg, cream, lemon, pepper):
- Parsleyfits better
- Tarragonfits about as well
- Nutmegthe original
- Capersfits about as well
Fit is the average pairing score against fish, shrimp, butter, egg, cream, lemon, pepper. Candidates are from the same food group and used in at least 100 recipes.
