Fill a pan one third full of water with half a tsp salt and bring to the boil
When it is boiling hold your bag of basmati rice about a foot above the water and pour it in a stream into the middle of the pan until the peak just breaks the surface of the water.
Stir the rice and return to the boil then cover and turn the heat right down to minimum. Set the timer for 10 minutes.
When the timer goes off DON’T lift the lid. Turn off the heat and leave for a further 10 minutes.
It will freeze and chill so don’t worry if you’ve made too much. The microwave is a wonderful gadget.
