Prepare the Dough:

1. Activate the Yeast:
   • In a large mixing bowl, combine warm water and sugar. Stir until dissolved. Sprinkle the yeast on top and let it sit for 5–10 minutes until foamy.
2. Mix the Dough:
   • Add the salt and 3 cups of flour to the yeast mixture. Mix until combined, then gradually add the remaining 1 cup of flour. Knead the dough for 5–7 minutes until smooth and elastic.
3. Let the Dough Rise:
   • Place the dough in a lightly oiled bowl, cover with a clean towel, and let it rise in a warm spot for 1 hour or until doubled in size.

Shape the Pretzels:

4. Divide the Dough:
   • Preheat your oven to 450°F (230°C) and line two baking sheets with parchment paper.
   • Punch down the dough and divide it into 8 equal pieces.
5. Form Pretzels:
   • Roll each piece into a 20–24-inch rope. Shape into a pretzel by forming a “U,” twisting the ends, and folding them back over the loop.

Boil and Bake the Pretzels:

6. Prepare the Baking Soda Bath:
   • In a large pot, bring 10 cups of water to a boil. Add the baking soda and stir until dissolved.
7. Boil the Pretzels:
   • Working one or two at a time, carefully drop the pretzels into the boiling water for 30 seconds. Remove with a slotted spoon and place on the prepared baking sheets.
8. Egg Wash and Salt:
   • Brush each pretzel with beaten egg yolk and sprinkle with coarse salt.
9. Bake:
   • Bake the pretzels for 12–15 minutes, or until golden brown.

Serve:

• Serve warm with mustard, cheese dip, or your favorite topping!
