Similar to a corn dog or pronto pup, but instead it is a hot dog wrapped in a delicious pretzel dough and baked. Takes some effort, but well worth the while. A nice honey mustard sauce is good for dipping.
Heat the beer in a saucepan over low heat until it reaches 110 degrees F (45 degrees C). Combine the warm beer, sugar, and 2 teaspoons kosher salt in a bowl. Sprinkle the yeast on top, and let stand for 5 minutes until the yeast softens and begins to form a creamy foam.
Place the bread flour and butter in a bread machine. Add the yeast mixture, then select the dough cycle.
Preheat an oven to 450 degrees F (230 degrees C). Line 2 baking sheets with parchment paper, or grease with vegetable oil. Beat the egg yolk in a small bowl with 1 tablespoon water; set aside.
Bring 10 cups of water to a boil in a large pot over medium-high heat, and stir in baking soda until dissolved. Meanwhile, turn the dough out onto a lightly oiled surface, and roll into a 10x20-inch rectangle. Cut the dough into 18 1-inch wide strips, then wrap each strip tightly around a hot dog, pinching the edges to seal, and leaving the ends open. About half an inch of hot dog should peek out of each end of the dough wrapper.
Drop 2 or 3 dough-wrapped hot dogs into the boiling water for 30 seconds. Arrange the boiled hot dogs on the prepared baking sheets. Brush each pretzel dog with the egg yolk mixture, and sprinkle with the remaining 1/4 cup salt.
Bake in the preheated oven until golden brown, about 15 minutes.
