I use a similar technique to cook rice – fill pan with required (washed) rice, cover with same amount again water and boil with lid on until all visable water has boiled off. Take off heat, DON’T remove lid and then start cooking your curry whilst it stands – keeps nicely hot for ages and cooks as it stands.
If you want ‘pilau’ style, flash-fry the rice in a little oil and some cumin seeds then add vegetable stock instead of water and use same technique.
EDIT – except I didn’t read that you use the technique for rice too. Ooops
