I seem to recall a thread a couple years back along the same idea, where it came out that canned sweet potatoes are impossible to find in the UK, and (at least then) fresh ones were pretty hard to find too. So not sure how the candied sweets will go. And of course, the fresh ones may be more readily available now since they're more popular in general, but I think canned sweet potatoes are a uniquely American thing.
