A carpaccio, of sorts. Sashimi-ish, perhaps. However you define this dish, I love it, as it takes sod all time to put together and looks rather impressive. A richer alternative would be salmon, or tuna, but I enjoy the delicate, fresh, lightness of a white fish like snapper – just make sure that it is really lovely and fresh. I like to serve this as a shared nibble with drinks – just give everyone a pair of chopsticks and let them dig in.
