Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Bisque of Lobster
Ingredients
Directions
Prepare the lobster
Cut the tender portions of the lobster into tiny cubes, about 1 cup.
Put the remainder of the lobster into the water and cook for 20 minutes, adding more water as it boils away.
Make the soup
In a separate pan, cook the flour and butter together, then add the milk and stir until smooth.
Add the salt, cayenne pepper, and white pepper to the mixture.
Strain in the lobster liquor and cook for 5 minutes.
Serve
Place the diced lobster into a tureen and strain the boiling soup over them.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lobster
- Provides the main flavour and the tender pieces that give the bisque its body.
- Flour
- Thickens the milk into a smooth, body-rich base when cooked with butter.
- Butter
- Adds richness and carries flavour when cooked with the flour.
- Milk
- Forms the creamy base of the soup, giving it smoothness and mild sweetness.
- Cayenne pepper
- Adds gentle heat that sharpens the rich, creamy flavour.
The step that matters
Thicken the milk with the flour and butter. Cooking the flour and butter together first forms a roux. Adding milk to it while stirring keeps lumps from forming and gives the soup a smooth, thickened texture.
Swap the white pepper
How well each one fits the dish's main ingredients (lobster, pepper, milk, butter, flour):
- Nutmegfits better
- Parsleyfits better
- Tarragonfits better
- White pepperthe original
Fit is the average pairing score against lobster, pepper, milk, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
