Ceviche is a form of citrus-marinated seafood appetizer, popular in mainly Latin American countries, such as South America, Guatemala, Mexico, and etc.For the most part everybody has there own variation of this dish, but for the most part it is a citrus-based mixture, with lemons and limes being the most commonly used. In addition to adding flavor, the citric acid causes the proteins in the seafood to become denatured, which pickles or "cooks" the fish without heat. Traditional style ceviche was marinated up to 3 hours. Modern style ceviche usually has a very short marinating period. With the appropriate fish, it can marinate in the time it takes to mix the ingredients, serve, and carry the ceviche to the table.
Clean scallops and put in a colander. Pour boiling water over them and let drain. Mix the onion and hot pepper (chopped very fine), garlic, mustard pickle, oregano, and vinegar. Put scallops into this mixture and let marinate for 30 minutes. Then add salt, pepper, olive oil, catsup, and lime juice. The lime juice should cover the mixture. Place in a glass container, cover and let stand in refrigerator 24 hours before eating. (Stir with a wooden spoon from time-to-time. Some metal spoons will tarnish from the acids.)
