In a mixing bowl, combine warm water, sugar, and yeast. Let it sit for about 5 minutes until frothy.

Add flour and salt to the yeast mixture. Mix until a dough forms.

Knead the dough on a floured surface for about 5 minutes until smooth. Place in a greased bowl, cover, and let rise for 30 minutes.

Preheat the oven to 450°F (230°C) and line a baking sheet with parchment paper.

Divide the dough into 8 equal pieces. Roll each piece into a long rope, about 24 inches long, and shape into a pretzel.

In a saucepan, bring 10 cups of water to a boil and add baking soda.

Carefully drop each pretzel into the boiling water for about 30 seconds, then remove and place on the baking sheet.

Brush the tops with beaten egg and sprinkle with coarse sea salt.

Bake in the preheated oven for 12-15 minutes until golden brown.
