CK, I have made your Bhuna using Admins new base and it was superb. I have had so many failures lately, I thought it would be impossible to get close to a BIR curry. But your Bhuna coupled with the new base is very, very close to the real thing and must be one of the best on this site.
It would possibly benefit from chicken stock and I made an adjustment at the end of cooking the Bhuna by adding some rose water and this gave it a real exotic taste.
Many thanks CK,
