When making a lobster dish, do not toss those shells. Make this delicious sauce from lobster shells and vegetables. The same method may be used with crab or shrimp shells. This recipe is taken from Prime Time Emeril by Emeril Lagasse and the sauce can be made up to two days in advance.

Lobster, crab, crawfish, and shrimp are crustaceans. Interestingly enough, they are characterized by a segmented body and an exoskeleton, and technically do not have shells. What is called the shell on these types of seafood is actually a carapace, but for simplicity and common usage, they are called shells. 

This sauce can be used to top seafood pasta, risotto, fish fillets, or steak for a surf and turf dish. It's sure to add rich, savory flavor to any dish.

Ingredients

  • 4 tablespoons unsalted butter (1/2 stick)
  • 1 tablespoon vegetable oil
  • 1/2 cup yellow onion (finely chopped)
  • 1/4 cup celery (finely chopped)
  • 1/4 cup carrots (finely chopped)
  • 2 tablespoons shallots (minced)
  • 1 tablespoon garlic (minced)
  • 2 tablespoons flour (bleached, all-purpose)
  • 1/4 cup cognac (or other brandy)
  • 1 to 1 1/2 pound lobster shells
  • 4 cups shrimp stock (or canned low-sodium chicken broth)
  • 3 tablespoons tomato paste
  • 1 teaspoon salt

Tips

  • Save shells from your lobster dinner for an economical and delicious sauce. Lobster shells can be stored in the fridge for up to a day after they are cooked.
  • The sauce can be stored in an airtight container in the refrigerator for up to two days.
  • Lobster shells are rich in flavor and can be used in all kinds of dishes. Make a lobster stock and use in soup, chowder, or risotto. Make a bisque by adding cream and cooked lobster meat.
