Personally I think its only us mad blokes who would exploit the Curry secret or a true recipe if one.
And what percentage are we in 5% may be
I know plenty of curry lovers who if told about a curry base are not interested
Its only us nutters with all our spices, pastes freezers full of precooked meat and graveys and not to mention
what a stinky house we live in

would bother
So I do not think our local TA or Indian Restaurant are are worried about us .I ts about being a good cook
Yes we can do a good sunday lunch but I still would go out for a good carvery
