You'll get there Prawnsalad; trust me. I usually use bhaji oil but you can get a similar effect by frying your spices carefully after the gg paste and tomato paste goes in. The trick is to cook the spices, infusing the oil, without burning them. It's all technique once you've got a good recipe. Oh and don't think the thing's done after a couple of minutes, they need a good simmer. I usually leave mine sitting, bubbling away for a good ten minutes while I have a pre-curry fag on the deck.
