Never, never, never, put dried fruit in a curry. Are you Australian by any chanc?. A friend of mine who lived in that country for a while, could never get to grips with their habit of putting dried fruit in curries. She used to refer to such dishes as Australian fruit salad.
My mother used to put sultanas in a curry - usually made with the remains of a lamb roast. I’m talking way back here, probably early 60s.
Actually I think fruit can go well with spicy lamb - AFAIK there are several e.g. Turkish/N.African dishes that combine spicy lamb with e.g. apricots.
