Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Fish stock
Forms the liquid base that carries the lobster flavour.
Butter
Enriches the soup and carries flavour as part of the thickening roux.
Flour
Thickens the soup, giving it body when cooked with the butter.
Egg yolks
Add richness and further thicken the soup when gently heated.
Cream
Adds richness and a smooth, velvety mouthfeel.

The step that matters

Adding the egg yolks. Egg yolks thicken by gentle heat but scramble if the soup boils. Stirring beaten yolks in gradually over low heat tempers them, so the bisque becomes smooth and silky rather than curdled.
