Well, I wish you luck Bob. When I came to retrieve the remains of the lamb from the Rishton Balti sauce this afternoon (by putting the whole lot in a colander and flushing it with hot water), I was staggered to find that the onion had not broken down at all, despite the fact that the curry was cooked for sufficiently long to render the lamb completely soft (i.e., far longer than would be required for chicken).
