I've just finished cooking the base (Half Batch), the G&G paste, the Bunjarra and then finally the Bhuna and I must say it was LOVELY!
I cooked everything exactly to the letter, except I used a 4 inch piece of Cassia in the Bunjarra because I didn't have any Cinnamon sticks and home made Garam Masala where called for.
I was a bit concerned about the Bunjarra because it was more of a reddy brown than 'brown sauce' brown, i'm thinking that might be because I added too much pureed tinned tomatoes (I added 4 tbsp based on Jeeras answer earlier in this thread).It still tasted fantastic though!
Once again, thanks very much Panpot!
