I recently came across canned rice pudding in Aldi here in Germany and it is almost on the same level of weird as the ice cream with licorice that a store close to me did or the one time I found chocolate infused with cafeine. I also don't really feel the apeal about pickled eggs...
BTW are hard boiled eggs a thing in your country? Here in Germany you can literally buy hard boiled eggs. Oh and we also have peeled and pre-cooked potatos in a jar o.o
What's the most unusual food you found?
