I did try the recipes from this site, only the BIR recipes, for me the onion paste recipe spoils it for me because of the addition of the water to blend, nearly every dish i made just tasted of raw onion.
If i can remember, it was a while a go now, i got so fed up with cooking the thing, takes too long and the final result wasn't that impressive.
I think it's an attempt at a bunjarra but does not quite get there.
I did use the base for other recipes after my attempts but didn't go back to it.
