Step 1
Heat the beer in a saucepan over low heat until it reaches 110 degrees F (45 degrees C).
Step 2
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.
Step 3
Place the bread flour and butter in a bread machine. Add the yeast mixture then select the dough cycle.
Step 4
Preheat an oven to 450 degrees F (230 degrees C).
Step 5
Line 2 baking sheets with parchment paper or grease with vegetable oil.
Step 6
Beat the egg yolk in a small bowl with 1 tablespoon water; set aside.
Step 7
Stir baking soda into 10 cups water in a large pot until dissolved and bring to a boil.
Step 8
Turn the dough out onto a lightly-oiled surface and roll into a 10x20-inch rectangle.
Step 9
Cut the dough into 18 1-inch wide strips then wrap each strip tightly around a hot dog in a spiral 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.
Step 9
Drop 2 or 3 dough-wrapped hot dogs into the boiling water for 30 seconds.
