I don't have a pressure cooker George but look forward to seeing what you did. I might consider getting one as that is an area of cooking I have not yet explored.
I sometimes use a process to make a simple base whereby I fry lots of onions until soft then just cover with water and place a lid on and boil hard, until the water has all but gone, stir, and repeat until the onions are more or less breaking down. It takes about 20 mins and produces great results.
I don't pre-cook chicken, I just don't see the need to or rather, I have never cooked enough to warrant doing so. I do feel that pre-cook meat does add to the dish, depending on the amount you flavour it of course. I often cook mine in a very hot oven (250c), place in a dish with a a little mix powder and mustard oil, cover with foil and pop in oven for 10-15 mins.
