Step 1

To make the rice, first wash it thoroughly in a sieve for 4 mins, gently turning it over by hand until the water runs clear. Drain the rice and put it in a pan with 540ml water.

Step 2

Leave it to stand for a minimum of 30 mins. It can be left overnight, but for best results, leave it for 30 mins-1 hr. Leave the soaking water in the pan with the rice and bring to the boil, put the lid on, reduce the heat and simmer for 8 -9 mins. Turn the heat off and let it stand with the lid on for a further 5 mins. Do not lift the lid.

Step 3

While the rice is cooking, to make the sushi-su, put the rice vinegar, sugar and 1 tbsp salt into a pan and leave on a low heat until the sugar and salt have dissolved. Be careful not to let it boil or the flavour will spoil. Remove from the heat and leave to cool.

Step 4

Put the rice into a wide flat dish such as a sushi oke, a baking dish or a roasting tray. Pour the sushi-su over the rice and fold it carefully into the rice with a wooden spoon as it cools down, being careful not to damage the grains. You can use a fan or a hairdryer on the coolest setting to speed up the cooling process, directing it at the rice. The sushi-su gives the rice more flavour and that familiar sticky glazed look.

Step 5

If you don’t want to use the rice immediately, cover it with a damp cloth so that it doesn’t dry out. Leave in a cool place, but do not refrigerate. The fridge will make the rice hard and dry, and the sushi-su helps to preserve the rice without refrigeration. Will keep for a day.
