In a large mixing bowl, pour in the warm water and stir in the granulated sugar until fully dissolved. Evenly sprinkle the active dry yeast over the water's surface and let it sit undisturbed for about 5 minutes, or until it becomes frothy, indicating that the yeast is active.
Add the all-purpose flour and the salt to the yeast mixture. Mix with a wooden spoon or your hands until a shaggy dough starts to form. Transfer the dough onto a floured surface and knead it for about 5 minutes, until it becomes smooth and elastic.
Form the kneaded dough into a ball and place it in a greased bowl. Cover the bowl with a clean kitchen towel or plastic wrap. Set it in a warm area to rise for about 1 hour, or until the dough has doubled in size.
Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper to prevent sticking.
Once the dough has risen, gently punch it down to release any air pockets. Transfer it to a floured surface and divide it into small pieces, roughly 1 inch each. Roll each piece into a small ball, ensuring they are uniform in size.
In a large pot, bring approximately 10 cups of water to a boil. Carefully whisk in the baking soda (use caution, as it may bubble up). Using a slotted spoon, gently drop in the pretzel bites, boiling each side for about 30 seconds. After boiling, remove them and place the bites on the prepared parchment-lined baking sheet.
Brush the boiled pretzel bites generously with melted unsalted butter, ensuring they are coated evenly. In a small bowl, combine the ½ cup of granulated sugar and 2 teaspoons of ground cinnamon to create the cinnamon sugar mixture, then sprinkle it generously over the pretzel bites.
Bake the pretzel bites in the preheated oven for 12 to 15 minutes, or until they are beautifully golden brown and puffed up.
Allow the pretzel bites to cool slightly on the baking sheet before serving them warm. Enjoy these delightful, fluffy bites straight out of the oven for the best experience!
Notes
