This lobster stock recipe is a luxurious broth made by simmering lobster shells with aromatic vegetables, herbs, and spices. Its rich, deep flavor profile combines the sweet, briny essence of lobster with savory notes from mirepoix—onions, carrots, and celery—enhanced by garlic, thyme, bay leaves, and occasionally a splash of white wine. This results in a broth that captures the ocean’s essence with a subtle sweetness and complex umami undertones.
