Start by combining the warm water, 2 tablespoons of granulated sugar, and active dry yeast in a large mixing bowl. Stir gently to ensure the yeast dissolves, then let the mixture sit for approximately 5 minutes until it becomes frothy, indicating that the yeast is activated.
Gradually add the all-purpose flour and salt to the yeast mixture. Mix until a shaggy dough begins to form. Transfer the dough to a lightly floured surface, and knead it for about 5-7 minutes, or until it becomes smooth and elastic.
Prepare a greased bowl and place the kneaded dough inside. Cover it with a clean kitchen towel, and set it in a warm place to rise for about 1 hour, or until it has doubled in size.
While the dough is rising, preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper for easy cleanup.
In a large pot, bring 10 cups of water and the baking soda to a gentle boil. This step is crucial, as it creates the chewy texture characteristic of pretzels.
Once the dough has risen, punch it down to release any trapped air. Divide the dough into 12 equal pieces. Roll each piece into a long rope, about 24 inches in length, and shape each rope into a twisted knot.
Carefully drop each pretzel knot into the boiling water for 30 seconds. Using a slotted spoon, remove the knots and place them on the prepared baking sheet, ensuring they are spaced apart.
Brush the tops of the pretzel knots generously with the beaten egg for a glossy finish. Combine the ½ cup granulated sugar and 2 teaspoons ground cinnamon in a small bowl, then sprinkle this mixture evenly over the knots.
Bake the pretzel knots in the preheated oven for 12-15 minutes, or until they attain a beautiful golden brown color.
When the knots are finished baking, remove them from the oven and brush them with melted butter for added richness and shine.
Notes
Serve warm with extra cinnamon sugar and a dipping sauce.
