I have had it several times at home, but have never cooked it myself. All that is required is to roast some peppers, simmer some sweetcorn and stock, and then blend. The peppers need to be roasted at gas mark nine, which my oven doesn't go up to, so I put it on the highest it would go (230 C , equivalent to gas mark 7) and put the tray right at the top. But then they ended up a little burnt! Which meant the soup didn't end up as 'sunshiney' a colour as it should have been. It still tasted pretty good though, so I can't complain too much!
3-leaf pepper hehe!
