In a medium saucepan with a tight-fitting lid, cover the rice with cold tap water. Swish the rice around until the water becomes cloudy, then slowly pour it out, using your hand to keep the rice from falling out of the pan. Repeat 2 or 3 more times until the water runs mostly clear, then drain well.
Add 175ml water and bring to the boil over a high heat. Once boiling, lower to a simmer and cover for 15-20 mins until the water is absorbed and the rice is soft. Do not lift the lid while the rice cooks. Remove the saucepan from the heat and let it sit, covered and undisturbed, for 10 mins. Uncover the pan and gently fold the rice over itself to fluff it up a few times before serving.
