I saw this trick tableside at a restaurant in Las Vegas. So easy to do at home and SO delicious.   1/2 pound Ahi sliced into cubes 2 tablespoons Madras curry powder, toasted in a dry pan Pinch of salt 1/4 cup canola oil ½ tablespoon finely julienned fresh ginger toast the curry powder in a dry pan - as it becomes fragrant add the oil and heat until near smoking. Stir in the ginger, remove from the stove, and immediately spoon a bit of the oil over one portion of fish. The fish should sizzle when the oil hits it; garnish with chopped chives and sesame seeds then serve immediately
