To form the rice beds, lightly wet your fingertips and palms. Take a walnut-sized amount of sushi rice (about 2 tablespoons / 30 ml / 1 fl oz) and shape it into a flat-bottomed, rectangular mound.
Repeat to create 12 rice beds.
Cut the nori sheets into twelve 1½ x 5-inch / 4 x 13-cm strips.
Wrap one strip, rough side facing inward, around a rice bed to create a 'wall'. Use a single grain of rice to glue the nori seam closed.
Repeat for all 12 pieces.
Arrange the completed rice beds on a serving platter. Carefully top each one with about 1 tablespoon (15 ml / 0.5 fl oz) of the Faux Roe and serve immediately.
Keep a small bowl of water nearby to frequently wet your hands, preventing the sushi rice from sticking to them.
