1. 1. Prepare the Dough: In a large mixing bowl, combine the sourdough discard, 1 tablespoon of granulated sugar, 1 teaspoon of baking soda, and 1/2 teaspoon of salt. Mix well until everything is incorporated. Gradually add the 1 1/2 cups of all-purpose flour, mixing until a shaggy dough forms. Turn the dough out onto a lightly floured surface and knead for about 5-7 minutes until it’s smooth and elastic. It should be soft but not overly sticky.

2. 2. Shape the Pretzel Bites: Divide the dough into 6-8 equal pieces. Roll each piece into a long rope, about 1/2 inch thick. Use a sharp knife or a bench scraper to cut each rope into 1-inch pieces. These will be your pretzel bites.

3. 3. Preheat Oven and Prepare Baking Sheets: Preheat your oven to 400 F (200 C). Line two large baking sheets with parchment paper or silicone baking mats. This prevents sticking and makes cleanup a breeze.

4. 4. Prepare the Water Bath: In a large pot, bring 4 cups of water to a rolling boil. Carefully stir in 2 tablespoons of baking soda until it dissolves. This alkaline bath is crucial for giving the pretzels their signature chewy texture and golden-brown crust.

5. 5. Boil the Pretzel Bites: Working in batches, drop the pretzel bites into the boiling baking soda solution. Let them boil for about 20-30 seconds, no longer. They will puff up slightly. Using a slotted spoon, carefully remove the bites, allowing excess water to drain off, and place them in a single layer on the prepared baking sheets.

6. 6. Bake to Golden Perfection: Transfer the baking sheets to the preheated oven and bake for 12-15 minutes, or until the pretzel bites are deeply golden brown and cooked through. They should have a nice, firm exterior.

7. 7. Coat with Cinnamon Sugar: While the pretzel bites are still warm from the oven, melt the 4 tablespoons of unsalted butter in a small bowl. In another shallow bowl, combine the 1/2 cup granulated sugar and 1 tablespoon ground cinnamon. Dip each warm pretzel bite into the melted butter, ensuring it’s fully coated, then immediately roll it in the cinnamon sugar mixture until evenly covered. Serve warm and enjoy!
