In a mixing bowl, combine the warm water and sugar. Stir in the yeast and let it sit for about 5-10 minutes until bubbly and frothy.

In a large bowl, mix the flour and salt. Gradually add the yeast mixture to the flour while stirring. Knead the dough for about 5-7 minutes until it’s smooth.

Form the dough into a ball and place it in a greased bowl, covering it with a clean cloth. Let it rise in a warm spot for about 45 minutes or until doubled in size.

Preheat your oven to 425°F (220°C). Bring a large pot of water to a gentle boil and stir in the baking soda.

Once risen, divide the dough into 8 equal pieces. Roll each piece into a long rope, about 20 inches in length. Shape it into a pretzel by making a loop and twisting the ends.

Gently lower each pretzel into the boiling water, one at a time, for about 30 seconds. Remove with a slotted spoon and place on a baking sheet lined with parchment paper.

Beat the egg and brush it over each pretzel. Sprinkle generously with coarse sea salt.

Bake the pretzels in the preheated oven for 12-15 minutes or until golden brown. Once out of the oven, brush them with melted butter for that irresistible flavor.
