Measure the water into a large saucepan, preferably a nonstick one, and place it on your largest hob ring. Bring it to the boil.
Pour in the brown rice, then move the pan to the smallest hob ring. It seems a bit of a faff, I know, but it will give you the best results. Pour in half of the milk, then add the honey, cinnamon and nutmeg, if using.
Simmer on the lowest heat for 30 m
