Ceviche is a non-cook prep method, letting the fish marinate and cook in citrus juices. The original recipe calls for Hamachi - also know as Amberjack - but this fish is not recognized by food.com. If you find it, use 1/2 cup of each type of fish. The ceviche needs to marinate for 1 hour so please plan ahead. Time for marinating is included in prep time.
