Lobster Soup

Ingredients

Directions

Make the stock base

  1. Slice the vegetables and fry them in the butter until pale brown.

  2. Stir in the flour, add the stock, and stir until it boils.

  3. Remove the shell from the lobster, cut the meat from the claws into dice, and set aside.

  4. Add the bouquet garni, the rest of the lobster, and the pounded shell to the stock, and simmer for 1 hour.

  5. Strain out the shell and rub the mixture through a fine sieve.

Finish and serve

  1. Return to the saucepan, add the milk, and bring to just below boiling point.

  2. Add the quenelles, anchovy essence, and season to taste.

  3. Place the lobster dice in a tureen and pour the soup over them.

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

What each ingredient does

Lobster
Provides the main flavour and the meat that is diced and served in the soup.
Butter
Fat that softens and browns the vegetables, building a deeper base flavour.
Flour
Thickens the stock into a smooth, lightly body-rich soup.
Milk
Adds creaminess and softens the flavour of the stock.
Fish stock
Forms the liquid base that the lobster and vegetables simmer in.
Carrot, turnip, celery, shallots
Sweet aromatic vegetables that build flavour in the soup base.

The step that matters

Keep the soup just below boiling after adding the milk. Milk can curdle or scorch when it boils hard, so heating it gently to just below boiling keeps the soup smooth and creamy.

Swap the celery

How well each one fits the dish's main ingredients (lobster, fish, milk, butter, flour, carrot, turnip):

  1. Capersfits better
  2. Parsleyfits about as well
  3. Celerythe original
  4. Tarragonfits about as well

Fit is the average pairing score against lobster, fish, milk, butter, flour, carrot, turnip. Candidates are from the same food group and used in at least 100 recipes.
