1. Divide the fish slices evenly among 6 plates. Combine juice and remaining ingredients; brush evenly over fish. Cover and chill 30 minutes. Serve immediately.
Safety Concerns: Always marinate meat and fish in the refrigerator. You can use some of the marinade for basting after removing the meat or fish from it only if you bring the marinade to a boil and cook for five minutes to kill any bacteria.
Although the acid in a marinade appears to â€œcookâ€� raw fish in seviche, it doesn't eliminate bacteria the same way cooking with heat does. When marinating fish that won't be cooked, make sure the fish is sushi-grade, or frozen-at-sea (FAS) fish; both are safe for healthy adults to consume raw.
