In a bowl, combine warm water and yeast; let sit until frothy (about 5 minutes). Mix in flour and salt until it forms a dough.

Knead the dough on a floured surface for about 5 minutes until smooth and elastic.

Place the dough in an oiled bowl, cover, and let rise in a warm spot until doubled in size (approximately 1 hour).

Divide the dough into equal pieces. Roll each piece into ropes and tie them into knots.

Boil water with baking soda; add knots one at a time for about 30 seconds. Transfer to a baking sheet.

Brush with melted butter mixed with garlic powder; sprinkle with additional salt. Bake at 425°F until golden brown (around 15 minutes).
