Plate of different sushi


Step 1. Cook rice 

Cook rice according to packet instructions. Leave cooked rice for 1 hour to cool down. 

Put cooked rice into the large bowl then pour 120ml of sushi seasoning on top of rice. Use spatula to mix them together but try not to squash rice. While you are mixing them use fan to cool the rice temperature down to body

Step 2. Make tuna mix 

Put drained tinned tuna, ¼ finely chopped onion and 120g Kewpie mayonnaise into a small bowl then mix together. 

Step 3. Roll Sushi 

Place seaweed on a bamboo mat. The size of seaweed can be modified by cutting it in half (if you want to make smaller sushi) .

Wet your hand with water. Spread the rice across the seaweed, and leave a 3 cm space along the top edge of the seaweed. 

Place the filling (tuna, cucumber, avocado, and rice seasoning) down the middle of rice. 

Use the sushi mat to roll the sushi gently, then squeeze and tighten over sushi mat with your fingers. 

Step 4. Cut sushi in pieces  

To cut a sushi roll, wet a bread knife with water or sushi seasoning. 

Cut a roll in 8 pieces and you have made your own sushi! Well done!
