Lobster Bisque

Ingredients

Directions

The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Make the base

  1. Pound the lobster shells and small legs finely in a mortar with the butter.

  2. Add this mixture to a pot with the fish bones, stock, shallot, herbs, and mace.

  3. Simmer for 30 minutes, then strain the mixture.

Finish the bisque

  1. Return the liquid to the pot, add cream, and heat gently.

  2. Whisk in the egg yolks and lemon juice just before serving.

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

What each ingredient does

Lobster shells
Release concentrated shellfish flavour and colour into the stock during simmering.
Butter
Carries the flavour of the pounded shells and adds richness and fat to the base.
Cream
Adds body, softness and a smooth mouthfeel to the finished bisque.
Egg yolks
Thicken the bisque and add richness when gently heated without boiling.
Stock
Forms the liquid base that extracts and carries the flavours of the shells.

The step that matters

Whisking in the egg yolks. Egg yolks thicken by setting when heated. If the bisque boils or gets too hot after they go in, they can scramble and turn grainy, so add them just before serving and keep the heat gentle.

Swap the mace

How well each one fits the dish's main ingredients (lobster, butter, whiting, shallot, cream, egg, lemon):

  1. Capersfits better
  2. Parsleyfits better
