In a medium mixing bowl, combine the active dry yeast and 2 tablespoons of granulated sugar in warm water. Stir gently and let it sit for approximately 5 minutes, or until the mixture becomes frothy, indicating that the yeast is activated.
In a large mixing bowl, whisk together the all-purpose flour and salt. Pour in the melted butter along with the yeast mixture. Combine all ingredients thoroughly until a shaggy dough starts to form.
Transfer the dough to a floured surface, kneading it for about 5-7 minutes until it feels smooth and elastic. If the dough is sticky, add a little more flour as needed.
Form the dough into a ball and place it in a greased bowl. Cover the bowl with a damp cloth and place it in a warm area. Let the dough rise for about 1 hour, or until it has doubled in size.
Meanwhile, preheat your oven to 425°F (220°C) and line two baking sheets with parchment paper for easy cleanup.
Fill a large pot with approximately 6 cups of water and bring it to a gentle boil. Carefully add 1/2 cup of baking soda to the boiling water—this will create a bubbly reaction.
After the dough has risen, punch it down gently and divide it into 8 equal pieces. Roll each piece into a long rope, approximately 24 inches in length, then shape each rope into a classic pretzel form by twisting the ends together.
One by one, carefully drop the shaped pretzels into the boiling water and allow them to cook for about 30 seconds. Use a slotted spoon to remove each pretzel, letting excess water drip off, and place them on the prepared baking sheets.
In a small bowl, mix together 1/2 cup of granulated sugar and 2 teaspoons of ground cinnamon. Brush the top of each pretzel liberally with the melted butter, then generously sprinkle the cinnamon sugar mixture over each pretzel.
Bake the pretzels in the preheated oven for 12-15 minutes, or until they are golden brown and aromatic.
