This is my own creation using both modern and traditional ceviche methods. The key of course is fresh fresh Ahi. There's nothing better. Like 'butter'. firstname.lastname@example.orgOne of the reasons that a really terrific Ceviche is , well, really terrific is the type of fish and/or seafood used. It MUST be absolutely of the freshest quality. A friend of mine and his girlfriend were recently in Hawaii and were raving about the quality of the Ahi there. We had a conversation on our foodservice professionals board ( www.restaurantbeast.com )about cryovac Ahi which is harvested in Hawaii and immediately IQF and placed in cryovac so that no oxygen can destroy it's freshness. Rumor has it that Roy Yamaguchi uses this type of Ahi for his restaurant in Palm Dessert (most likely not for his famous in Hawaii). My version is a bit of a cross between two different styles. Shrimp that has been quickly blanched pink, halibut or other sushi-grade fish can also be used in place of the Ahi.
