Sushi Rice - The 10% Rule
Ingredients
180 ml Rice Vinegar
45 g Sugar
(about 3.5 tbsp)
18 g Salt
(about 1 tbsp)
Instructions
- 1
Start by cooking the rice.
Rinse the rice, then cook it in your rice cooker. Because sushi vinegar will be added later, it helps to use slightly less water than usual so the rice cooks a little firmer.

Make the sushi vinegar.
Combine 180 ml rice vinegar, 4 to 5 tablespoons of sugar and 1 tablespoon of salt. Stir well until the sugar and salt are fully dissolved. There is no need to heat it. If you have leftover sushi vinegar, keep it in a glass bottle or jar in the fridge. It should keep well for a couple of months.

Prepare your tools.
You will need a rice paddle and a large bowl. A wide, shallow bowl works well, and if you happen to have a traditional wooden sushi tub, that can be nice to use too because the larger surface makes it easier to mix the sushi vinegar evenly and cool the rice quickly. If you are using a wooden sushi tub, dampen it first, let it absorb a little moisture, then wipe away any excess water. It also helps to have something ready to fan the rice with, such as an uchiwa or even a paper plate, along with a damp cloth or cling wrap to stop the rice from drying out.

Add the sushi vinegar and cool the rice.
Transfer the freshly cooked rice to a large bowl. Pour the sushi vinegar evenly over the rice, letting it run down the rice paddle so it spreads more gently. Start mixing from the bottom with large, gentle movements. Once the vinegar is distributed, use a cutting motion with the paddle to break up any clumps. Try not to crush the grains, because you want the rice to stay fluffy and separate. As a general guide, about 10% of the cooked rice weight can be used for sushi vinegar. For example, 400 g of cooked rice would use about 40 ml of vinegar. As you mix, spread the rice out and cool it quickly with an uchiwa, or anything you can fan with, gently turning the rice now and then until it reaches about body temperature. This quick cooling helps give sushi rice its glossy finish.

Cover and keep at room temperature.
Once it has cooled, cover it with a damp cloth or cling wrap so it does not dry out. Do not refrigerate it, because the rice will become firm. Keep it at room temperature until you are ready to use it.
Tomoka's Note
I find it helpful to keep a simple sushi vinegar guide on hand, especially when I am making different amounts of rice. For 2 cups of uncooked rice: - 65 ml rice vinegar - 16 to 17 g sugar (about 1 tbsp + 1 tsp) - 6.5 g salt (about 1 tsp) For 3 cups of uncooked rice: - 100 ml rice vinegar - 25 g sugar (about 2 tbsp) - 10 g salt (about 1 2/3 tsp) A simple approach is to add the sushi vinegar gradually, tasting as you go until it feels balanced. To be honest, I often use store-bought sushi vinegar instead of making it from scratch. It is easy, reliable and gives very consistent results, and you can usually find it at Japanese grocery stores. This is the one I am using at the moment:
If you prefer to make it from scratch, you can often find rice vinegar at supermarkets like Coles and Woolworths in the Asian foods aisle. If you cannot find it locally, this is the one I use: Carwari organic rice vinegar. The sushi vinegar ratio in this recipe gives a slightly stronger flavour, with a clear balance of tanginess, sweetness and saltiness. I think it works especially well for sushi rolls and hand rolls, but for sweeter styles such as inari sushi, you may prefer to reduce the sugar and salt a little. If this is your first time making sushi rice, or if your rice turns out softer than expected, try adding a little less sushi vinegar to begin with, then taste and adjust. If you have leftover sushi rice, it can become firm after refrigeration. You can gently warm it in the microwave or a steamer to soften it again. If the vinegar flavour feels lighter after reheating, add a small amount more if needed. Sushi rice can feel a little tricky at first, but once you understand the balance of vinegar, sugar and salt, it becomes much easier. I hope this helps you feel more confident making sushi rice at home.
