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 ↓
Crab Bisque
Ingredients
Directions
Stew the vegetables and crab
Melt the plain butter in a saucepan over low heat, avoiding a hiss.
Add the minced onions, pepper, and tomato; season with salt and pepper, cover, and stew for 20 minutes.
Add the crab meat and a little boiling water to prevent sticking, then stew for 10 minutes.
Finish the bisque
In a separate vessel, heat the milk with a pinch of baking soda.
Thicken the milk with the floured butter and season with salt and cayenne.
Remove the saucepan from heat and stir in the thickened milk.
Pour the bisque over the fried bread cubes in a tureen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Crab meat
- Provides the main flavor and the substance of the bisque.
- Milk
- Forms the creamy liquid base that the bisque is built on.
- Flour
- Thickens the milk with the floured butter, giving the bisque body.
- Onions
- Add sweetness and aroma as they stew down into the base.
- Tomato
- Adds acidity and body as it softens with the onions and pepper.
- Green sweet pepper
- Adds fresh, slightly bitter vegetable flavor to the stewed base.
The step that matters
Stirring the thickened milk into the pan off the heat. Adding the hot thickened milk to a boiling mixture can make it curdle or separate. Removing the pan from heat first lets the milk blend in smoothly and keeps the texture even.
