I guess I am dating myself. But, Halloween treats in my location were often homemade items. Fresh oranges and apples were often given out. Sometimes homemade cookies of various kinds.
However, my least favorite were popcorn balls. They were balls of popped popcorn held together with some sort of sticky syrupy liquid that hardened. They were often salted. And, of course, cold rather than warm. I suppose warmed they probably tasted o.k. But, I remember them as cold, dry, and somewhat stale. They were often wrapped in colored paper that stuck to them and had to be peeled off.
Mom often went through our bags of goodies when we got home and discarded lots of questionable goodies first, unless we ate them before we went home. I can remember occasionally getting sick the next day and had to stay home from school for a day or two. That was Halloween in my day and location.
