I had mutton curry during my 3 visits to Delhi last year and it was like a very rich lamb bhuna.
It was only on my last visit that it was explained to me that in India mutton is goat meat.
Very rich curry, strong tomato flavour and moderate to madras heat. with a thick sauce.
I really enjoy it.
as for Jamaican curry goat, its worlds apart.
Jamaican curry is much more like a Jerk flavour
