In a large mixing bowl, combine warm water, yeast, and sugar.

In a separate bowl, whisk together flour and salt.

Gradually add the flour mixture to the yeast mixture, stirring until a dough forms.

Turn the dough onto a floured surface and knead for about 5 minutes.

Place the dough in a greased bowl, cover with a towel, and let it rise for about 1 hour.

Preheat your oven to 425°F (220°C). Divide the dough into 12 equal pieces, roll each piece into a long rope, and shape it into a pretzel.

In a small saucepan, bring 4 cups of water to a boil and add the baking soda.

Dip each pretzel in the baking soda bath for about 30 seconds, then place them on a parchment-lined baking sheet.

Bake for 12-15 minutes until golden brown.

Brush the pretzels with melted butter immediately after baking.
