An easy nutritious seafood soup. It's bland for our tastes - I would probably double all the seasoning ingredients (onion, garlic, cumin, allspice). There also seems to be way too much broth - I would at least half the amount of clam juice. I did some Caribbean-style substituting. (I think this is a dish that authentically would be made with whatever you had.) My seafood was clams, mussels, shrimp, octopus, and squid. Along with the sweet potato, I included some boniato and green plantain. I also omitted the cilantro.
