Why it works: Pepper and parsley 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 ↓
Fish Bisque
Ingredients
Directions
Heat the stock in a pot until it boils.
Stir in the minced fish, pepper, salt, parsley, and butter.
Combine the scalding milk with the white roux and pounded cracker.
Boil the mixture once.
After the fish has cooked for five minutes, stir the thickened milk mixture into the fish.
Optionally add a well-beaten egg to the milk and crumbs before serving.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Halibut or other white fish
- Provides the main body and flavor of the bisque as the soup's base protein.
- White roux
- Thickens the milk mixture so the bisque becomes smooth and creamy.
- Milk
- Adds creaminess and mild sweetness, and combines with the roux to form a thickened base.
- Pounded cracker
- Adds body and helps bind the thickened milk mixture.
- Good stock
- Forms the liquid base that carries the fish and other ingredients.
The step that matters
Stirring the thickened milk into the fish. Adding the milk mixture after the fish has cooked for five minutes lets the fish set while the roux-thickened milk blends in smoothly. Boiling the mixture once thickens the starch in the roux, which helps prevent lumps and a thin, uneven texture.
Swap the parsley
How well each one fits the dish's main ingredients (fish, pepper, butter, milk, egg):
- Parsleythe original
- Nutmegfits about as well
- Tarragonfits less well
- Cinnamonfits less well
Fit is the average pairing score against fish, pepper, butter, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
