1. Combine the warm water, sugar, kosher salt, and active dry yeast. Allow the yeast mixture to activate.
2. Add the all-purpose flour and melted butter. Mix until the ingredients form a cohesive dough with a smooth, workable consistency.
3. Set the dough aside and allow it to rise until it has noticeably increased in size.
4. Divide the risen dough into portions. Roll each portion into a long rope and shape each rope into a traditional pretzel shape.
5. Bring the 10 cups of water to a boil in a large pot, then carefully add the baking soda.
6. Place the shaped pretzels into the baking-soda bath briefly, then carefully remove them and transfer them to a prepared baking sheet.
7. Combine the egg yolk with 1 tablespoon of water. Brush the mixture over the pretzels and sprinkle with pretzel salt.
8. Bake the prepared pretzels until golden and cooked through. Allow them to cool slightly before serving.
