This dish is ridiculously simple and refreshing. You can use any fish you might find at any reputable sushi restaurant.
Juice of 1/2 to 1 lime
Extra virgin olive oil to taste
2-3 large basil leaves, chiffonade
1/2 red Thai chile, halved, seeded and thinly sliced
Sprinkle of Fleur de Sel
Put fish in freezer until it is very cold. With a very sharp knife slice thinly and arrange anyway you want or on any serving plate you wish.
Squeeze lime juice on fish first, then oil. Sprinkle Fleur de Sel, add sliced chile and basil. you could use coriander if you prefer as well. Enjoy!
