I been after bir methi curry recipe for years and I haven't had much look at all, there is not much on the internet, e-books and takeaways that still this curry on their menu are are reluctant to give it away. Can anyone give me a recipe for this curry as bir measurements are fine because that's what i mainly use anyway.

If anyone could help on this I would be so gratified and would be happy to help anyone who has any questions in return.
