Caldo de siete mares—“soup of the seven seas”—shares characteristics with other seafood stews from across the globe. Legend has it that, like cioppino or bouillabaisse, it was created out of necessity, a way for fishermen in the Ensenada area of Baja California to use up their unsold catch. And like all great seafood soups, the key to a killer caldo de siete mares is a super flavorful stock. Here, we quickly infuse chicken or seafood stock with aromatics—alliums, carrots, dried chiles, tomatoes, warm spices, bay leaves, and <a href="https://www.chefsteps.com/recipes/mariscos-sazon">my flavor-bomb Mariscos Sazón</a>, which includes umami-rich dried shrimp—as well as fresh shrimp shells. That “quickly” isn’t for convenience, it’s for maximum flavor: The volatile aromas in shrimp shells that we associate with “shrimp flavor” are quickly extracted through cooking, and you’ll get diminishing flavor returns if you simmer the stock for hours. Puréeing and straining the stock (shells and all) yields a super aromatic soup base with plenty of body, which serves as a perfect backdrop for all the seafood.With the stock taken care of, you can focus on seasoning and cooking each piece of seafood perfectly. We stagger the seafood cooking in stages, rather than dumping everything in the pot at once and either hoping for the best or fishing things out one at a time as they’re ready. The reward for attention to detail? Tender seafood and a super savory broth that gets a final flavor boost from shellfish liquor as the clams and mussels open up right before it&#39;s time to serve. This is the way.
