Combine lukewarm water, yeast, salt, and sugar in a mixing bowl. Stir gently and let it rest for 1-2 minutes.

Gradually mix in bread flour, stirring until a rough dough forms, then knead for 4-5 minutes until smooth.

Shape the dough into a ball, place in an oiled bowl, cover, and let it rest for 15-20 minutes.

In a pot, boil 10 cups of water and stir in baking soda to create an alkaline solution.

Punch down the dough and divide into 8 pieces. Roll each into a 24-inch rope and shape into pretzels.

Lower pretzels into the boiling baking soda bath, soaking for 30 seconds each before placing on a baking sheet.

Preheat oven to 450°F. Whisk egg yolk with water, brush on pretzels, and sprinkle with salt. Bake for 12-14 minutes.

Transfer pretzels to a wire rack to cool for a few minutes before serving.
