Instructions

1. 1
   Rinse rice multiple times until water runs clear; cook in a rice cooker with slightly less water than normal.
2. 2
   Mix rice vinegar, sugar, and salt over low heat until dissolved. Fold gently into cooked hot rice using a slicing motion; cool to body temp.
3. 3
   Slice fresh fish at a 45-degree angle into clean, uniform rectangles.
4. 4
   Wet hands with water-vinegar mix. Shape a small oblong ball of rice (approx. 20g) in your palm.
5. 5
   Dab a tiny speck of wasabi onto the fish slice, place fish over the rice ball, and press gently with two fingers to mold together perfectly.
