Shellfish Stock

When working with shellfish like cockles, mussels, and razor clams, the cooking liquor they release is liquid gold for sauce-making. The technique of using the stock from multiple types of shellfish to build a chowder or veloute creates layers of complex, deep seafood flavour that a single type alone cannot achieve. Cook each shellfish type just until it opens, then strain and combine the liquors. Be extremely careful not to overcook shellfish, as overcooked mussels, cockles, and razor clams become rubbery and tough. The combined stock can be reduced and enriched with cream and aromatics like ginger to create a rich, warming chowder sauce with remarkable depth.
