Ingredients (Makes 8-10 rice balls)

  • 1/2 fillet salted mackerel (filleted) (80 g)
  • Tempura flour mix (store-bought), as needed
  • 400 g cooked rice (hot)
  • 30 g benishoga
  • 8-10 pieces toasted nori (full sheet cut into 6 equal pieces)
  • 2/3 tsp salt
  • Oil for deep frying

Directions

1

Mince the benishoga and mix with the rice along with 2/3 tsp of salt.

Advice

Adding benishoga helps to balance out the oiliness of the tempura.

2

Use fish bone tweezers to remove any fine bones that may be present in the mackerel. Cut into 8-10 equal pieces and dust with tempura flour mix.

3

Combine 40 g of tempura flour mix with 70-80 ml of water to make the batter. Dip the fish into the batter and deep fry in oil heated to 170 degrees Celsius. Remove and drain on a rack.

Advice

Mackerel is a great fish for tempura. Crispy fried mackerel is delicious all on its own.

4

Divide the rice into 8-10 equal portions. Take one portion and place it on a piece of plastic wrap. Make a well in the center to place one piece of tempura. Gather up the ends of the plastic wrap, twist and squeeze. Shape into a triangular rice ball.

Advice

Place the plastic wrap over a small dish with curved edges. You'll find it much easier to gather up the ends to form the rice ball.

5

Repeat the process to make the other rice balls. Wrap each one with a piece of nori.
