A mate of mine was making us a curry with a jar of pataks balti sauce,i asked for a taste of it out the jar and the first thing that sprang to mind was that it tasted similar to a bir kitchens tomato sauce i once sneaked a taste off,it tastes mildly tangy and quite tomatoey,so as i like to experiment i went and bought a jar and liquidized it and i made some bir curries using the same amount of the balti sauce instead of using the watered down tomato puree version to cook the spices in ,the curries i have made are so much tastier,i feel it was a big step forward and i wont be turning back,maybe the purists may not like it so perhaps they could look at the ingredients on the jar and have ago at making your own
