I love when Aldi brings out these lovely specialty items. Often they are imported (I think this was from Germany.) The downside is that they are limited time products and when I find them and fall in love with them, they're often gone on the next visit.
I was lucky enough to stop back and find that they were still in stock and scored a couple more bags. My son ate one whole bag in a sitting. They are totally addictive. If you come across them, buy a bag (or 10) to try.
