Ceviche is raw seafood or fish “cooked” by lemon or lime juice. The acid in the citrus juice denatures the proteins in the fish, causing it to become opaque and producing a firm texture. Now don’t wrinkle your nose… it’s invigoratingly delicious as long as you use the freshest of ingredients! Ceviche is equally appreciated as a finger food, appetizer or salad. One made with fresh white sea bass is a favourite.
