Lobster Bisque

Ingredients

Directions

Prepare

  1. Split the lobster down the back and remove the meat.

  2. Break the claws and pound the shells in a mortar until fine.

Make the bisque

  1. Mix the pounded shells with the butter in a stewpan and heat until hot.

  2. Add the flour and cook for 10 minutes.

  3. Moisten with the wine and fish stock, then add the vegetables, bouquet garni, and peppercorns.

  4. Stir until it boils, then reduce heat and simmer for 20 minutes.

  5. If too thick, add more stock.

  6. Strain through a tammy cloth.

Finish and serve

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

What each ingredient does

Lobster shells
Provide the concentrated shellfish flavour that gives the bisque its character.
Butter
Carries the shell flavour and adds richness to the base.
Flour
Thickens the bisque as it cooks with the butter and liquid.
White wine
Adds acidity and aroma that brighten the rich stock.
Cream
Adds smoothness and richness to the finished soup.
Fish stock
Forms the liquid base that the bisque simmers in.

The step that matters

Adding the flour and cooking it for 10 minutes. The flour must cook in the hot butter long enough to lose its raw taste and thicken evenly; undercooked flour leaves a pasty flavour and lumps, while the later stock addition should be done gradually to avoid clumping.
