Recipe. Really really good with butternut squash bisque. Also I made these a few weeks ago and had a sandwich with pimiento cheese, bacon, mustard, and caramelized onions. The bun couldn't hold it together but the flavor combination was incredible.
Pretzel buns are one of my favorite types. I usually make them rectangular if if using them for sandwiches though.
My recipe is also more like a Bavarian pretzel though, only flour, water, salt, and yeast or starter, not both. The flavor is also better with a lye bath instead of baking soda. It's a dead simple 50% hydration, so it easily scales.
Yours look very nice
