Tomorrow's Opening Day here in St. Louis. Although I'm unable to attend, my office mates and I will be honoring it with an authentic Chicago Demon Dog Hot Dog Bar. Fun! I wanted to bring in as much authentic as I could and could not find poppy seed hot dog buns for sale. So I decided to make them myself. When I saw a YouTube video from Rhodes on how to transform their dinner rolls into hot dogs, I knew I could simply add the poppy seeds myself, so that's what I did. Although I love homemade bread, I needed a shortcut with my limited time on the weekends. These are semi-homemade hot dog buns made from store-bought frozen dough. Combine two dinner roll balls and form into one hot dog bun.
