Lobster Soup

Ingredients

Directions

Thicken the milk

  1. Heat the milk in a saucepan over boiling water until it boils.

  2. Dissolve the corn starch in a little cold water, then stir into the boiling milk.

Cook the lobster

  1. Cut the lobster into very small pieces and place in a pint of boiling water with salt, mace, cayenne pepper, and butter.

  2. Boil until the lobster is cooked through.

Combine and finish

  1. Strain the lobster mixture and pour into the thickened milk.

  2. Pound the coral finely and add it to the soup for a pretty pink color.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Lobster
Supplies the main meaty texture and sweet flavor of the soup.
Milk
Forms the creamy base that the thickener sets into.
Corn starch
Thickens the hot milk as its granules swell, giving the soup body.
Butter
Adds richness and a smoother, rounder mouthfeel to the broth.

The step that matters

Dissolving the corn starch. Starch dispersed in cold water hydrates evenly, while dry starch dropped into hot liquid clumps. Once heated, the granules swell and thicken the milk, so the mixture should be stirred as it is added.

Swap the mace

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

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

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