Wash the rice thoroughly until the water remains clear. Bring rice and 75 ml water to the boil in a closed pot. Turn off the heat and let the rice swell for 20 minutes. Remove the pot from the heat and let the rice steam for another 20 minutes in the open pot. Season rice with vinegar, salt and sugar and place on a tray to cool.

Put one fish and 2 cucumber strips in each. Roll up with the help of the bamboo mat, pressing the sushi roll lightly with your hands.
