Steamed white rice takes 15 minutes to cook on the hob. Here is how I cook it, its simple and never fails.

You will need a pan (preferably heavy bottomed) with a lid (as we are going to steam the rice for the last 10 minutes).

Palm full of rice per person

Rinse it, then add water (it should be an inch above the rice).

Bring to a boil and boil for 4 minutes (7 if brown or whole grain) stirring it often.

Cover with lid (ensuring that steam doesn't escape, I tend to use a frying pan for this, as I seem to have lost all the lids)

Reduce heat and wait 10 minutes. (15 for brown)

Perfect steamed rice in less than 15 minutes. I've also used water from a kettle then I boil the rice for just 3 minutes.
