Fish Stock
Fish stock is a delicate broth, cooked briefly and gently for best flavor. Bones and heads are used for flavor and body. They should be washed and cleaned of gills and organs to make a clear, clean-tasting stock. White-fleshed fish are best; salmon, mackerel, or other oily fish have too strong a flavor. If not buying whole fish, ask your fishmonger for clean heads and bones for making stock.
