Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the base and carries flavour as the roux's fat.
- Flour
- Thickens the bisque with the butter, giving it body.
- Milk
- Forms the liquid base that becomes the creamy body of the soup.
- Oysters
- Provide the main seafood flavour, infused into the milk as they cook.
- Cream
- Adds richness and a smoother, silkier texture.
- Egg yolks
- Add richness and thicken the bisque gently when stirred in at the end.
The step that matters
Adding the egg yolks. Egg yolks thicken by gentle heat. If the bisque is boiling when they go in, they can scramble and turn grainy. Add them off the heat or at very low heat, just before serving.
