First thing's first, make sure your wok is very hot before adding the oil and always use cold, cooked rice - it doesn't even matter if it's been cold for a couple of days.
Once you've added the rice, make sure you push it right out to the sides of the wok to ensure that every grain gets cooked. Long grain rice - such as basmati - is best.

Constantly stir the eggs into the rice using a wooden spatula to ensure that the rice absorbs all the egg.
Sliced spring onions are a nice finish to egg fried rice.
