“Fumet” is the French term for an aromatic broth (typically fish or vegetable, though it can also refer to a meat stock) that is simmered down to concentrate the flavors. Making your own fish stock is easier than you think and adds irreplaceable flavor to recipes, such as Gulf Coast Bouillabaisse (p. 220) and Southern Shrimp Stew (p. 228). Whatever you don’t use can be frozen in small plastic containers (for up to 2 months), so you can pull it out for quick seafood pasta, risotto, or poaching liquid for a fresh fillet.
Cooks' Note
An alternative to fish fumet is the strained juice from mussels steamed in white wine with herbs. Or feel free to add a few mussels to the pot with your fish bones for a really rich and tasty fumet.
