I've tried a few different versions, but currently use Mick's recipe (Curry Barking Mad).
As he states in his book "There are much longer winded ways of doing it, but this gets good results."
I cooked up a batch of gravy beef last wek in the pressure cooker, it literally fell apart in your mouth, no chewing required at all, it was excellent. Chicken is always very tender too. Probably the worse result I had was Curry 2 Go recipe, that involved yogurt and an over night marinade, and it was not as good as CBM's
Ashoka recipe is good, but not THAT much better than Mick's considering the extra work IMHO.
It's easy and it works. I don't know whether I am at liberty to print the recipe here, as it is from HIS book.
I will definitely try your recipe though Rich.
