This is simplicity itself, place the rice and sugar in the ovenproof dish, pour in the milk and the evaporated milk and give it all a good stir.
Grate the whole nutmeg all over the surface (it may seem a lot but it needs it), then, finally, dot the butter on top in little flecks. Next just carefully pop the dish in the oven on the centre shelf for 2¼ hours. After the pudding has had 45 minutes slide the shelf out and give everything a good stir.
At the end of this time the rice grains will have become swollen, with pools of creamy liquid all around them, and, of course, all that lovely skin!
