This does seem logical as with mostly Bir dishes you taste the hot Spicy Oil around your mouth but with supermarket dishes it is a different story, so Oil is a very big decider (Again!), but it does look, to get that sort of effect that you would use large amounts of Oil & therefore must be skimmed, but it looks like a very important thing about bir style cooking technique is knowing how to make it Oily but not too Oily, i seem to go one way or another when it comes to Oil quantity, much too learn have i :-[ .
