Lobster stock is a special item. It isn't every day you get a chance to enjoy the richness of lobster meat, and with the seafood treasures being so expensive, every cook should have a recipe to make use of the leftover bodies and shells. This recipe is for lobster stock, but you can concentrate it and add a bit more salt to make a rich lobster broth, too. Use this as a soup base, or for a fantastic lobster risotto.
