If you haven't had ceviche, you are in for a real treat. You can make this with shrimp, fish, or scallops. Be aware that the seafood is not cooked in the traditional way, but is "cooked" in the lime juice mixture. There is a chemical process that occurs when the acid of the citrus comes in contact with the fish is similar what happens when the fish is cooked, and the flesh becomes opaque and firm. This ceviche is fresh and delicious!! Enjoy!
