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.

Prepare the lobster

  1. Boil the lobster for about 15 minutes, then remove and chop it finely.

Make the bisque

  1. In a separate bowl, mix the butter and flour together until smooth.

  2. Add the mace, pepper, and beaten egg to the butter-flour mixture.

  3. Gradually stir in the milk and bring to a boil.

  4. Add the chopped lobster to the mixture and serve immediately.

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 meaty body of the bisque.
Butter
Adds richness and fat, carrying flavour through the bisque.
Flour
Thickens the liquid, giving the bisque a smooth, body-rich texture.
Egg
Enriches and thickens the bisque slightly when combined with the warm milk.
Milk
Forms the creamy liquid base that makes up most of the soup.

The step that matters

Gradually stir in the milk and bring to a boil. Adding milk slowly to the butter-flour mixture keeps it smooth, without lumps. Bringing it to a boil thickens the starch from the flour, which sets the soup's body. Heating too fast or unevenly can scorch the milk or curdle the beaten egg.

Swap the mace

How well each one fits the dish's main ingredients (lobster, butter, flour, pepper, egg, milk):

  1. Nutmegfits better
  2. Parsleyfits better
  3. Tarragonfits better
  4. Macethe original

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