Lobster Soup
Ingredients
Directions
Make the stock
Remove the meat from the lobster and break up the shell.
Combine the lobster shell, small claws, and heads of the shrimps with enough water to cover them.
Stew for 30 minutes.

Lightly brown the onions, carrot, turnip, mace, peppercorns, cloves, bay leaves, parsley, marjoram, and celery in a stewpan.
Add the chicken feet and veal or fish stock.
Stew for 1.5 hours.
Prepare the pounded mixture
Cut the lobster meat into dice-sized pieces and set aside.
Pound the cream and meat from the lobster head and coral with the picked shrimps.
Season with cayenne and nutmeg.
Moisten with garlic vinegar.
Mix the reserved lobster liquid with the pounded mixture.
Finish and serve
Add essence of anchovy to the tureen.
Skim and strain the soup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hen lobster
- Provides the main shellfish flavour and the tender meat added at the end.
- Shrimps
- Their shells and heads build the stock, and picked meat is pounded into the soup for body.
- Chicken feet
- Release gelatine during long stewing, giving the soup a fuller, silkier body.
- Hard-boiled egg yolks
- Add richness and a smooth, mealy texture to the finished soup.
- Essence of anchovy
- Adds a salty, savoury depth that rounds out the seafood flavour.
The step that matters
Pounding the lobster head, coral and shrimp meat with the stock. The pounded mixture thickens and flavours the soup, so it must be fully broken down and mixed in evenly. Lumps stay grainy, and the coral's fat and flavour only spread through the liquid when it is finely worked.
Swap the mace
How well each one fits the dish's main ingredients (lobster, shrimp, onion, carrot, turnip, clove, parsley):
- Celeryfits better
- Capersfits better
- Thymefits better
- Macethe original
