It does sound quite similar, though Cranachan seems to often have berries with it.

Fuarag also has a divination history - kinda - as things like a coin, wedding ring, and something else were put in, with the items telling the future of the one who found them. I've only read that and never heard of it being done in Cape Breton.

Sitting here now after the trick or treaters have finished mowing into a bowl of it!
