I'v been making curries for some 40 years, in the early days the lack of spices and little information mean't many failures. I cracked the base sauce some years ago using a variety of sources, however decided to give this a go and along with the spiced oil & Masala spice cooked a chicken Jalfrezi last night, it was the nearest I have  got to BIR curry. I will definately be using this combination for my curries in the future, well done a real top job.

P.S. just received some "Dorset Naga chillies so here goes for a vindalo.
