Natco say: "There are many forums and links to sites that have their own opinions about this topic and believe me, we have tried most of them and found them to be lacking." They can't have missed this forum, so it appears they are none too impressed.
I understand red onions are widely used in 'authentic' Indian cuisine, not least since they are closer to the type of onions most readily available in India. But has anyone ever seen sacks of red onions in BIR's?
Notwithstanding any reservations, these are grand claims by Natco, just like all the claims by many rip-off authors before. If these recipes do not produce the 'holy grail' of curries, just what are Natco playing at? Therefore, I am optimistic that they will.
