Ostiones estilo GuaymasGuaymas is an active seaport town on the Gulf of California. Commercial fishermen routinely bring in boatloads of shrimp and oysters to be marketed locally or exported. During one of our trips to Guaymas we had broiled oysters like this made with the fresh catch.Most fish markets in the United States will have fresh oysters in season. Oysters must be very fresh with shells tightly closed. If purchased without shells, the oyster liquid should be clear. If it is milky in color, do not use them. Serve fresh corn tortillas and a bowl of fresh salsa with the oysters.
