Shave the clams and clean them. Clean the squid and be sure to remove their insides unless you bought them
already cleaned. Wash the shrimps. Remove head, tail and insides from the merluza. Cut it in pieces without removing
the backbone. Put all seafood, except clams, in a bowl. Make your own fish broth using head and tail of the merluza
and some instant stuff. Cook the clams in the broth until they open and keep them apart for later.
