This is also a very traditional Hungarian dish that is made with either prune plums or cherries. gombocz (dumplings).
These were great, i normally make the quark/sourcream version with prune plums-which turned on me so used regular, and was always afraid to try the potato version. Yummy and not difficult. I baked the potatoes which had an added benefit of making the skin strong enough to be lifted off with a fork immediately. Thanks for posting these Kate, when i get my next batch of prune plums will try this way as well.
