1. Preheat the oven to 400°F (200°C) and line two baking sheets with parchment paper.

2. In a large bowl combine sourdough discard, melted butter, sugar, and salt then gradually add flour until a soft dough forms.

3. Knead the dough briefly until smooth, dividing it into four equal portions and rolling each into a ½ inch rope.

4. Cut the ropes into 1 inch pieces and arrange the bites on the prepared baking sheets.

5. Bring six cups of water to a boil, stir in baking soda, then boil pretzel bites in batches for 30 seconds before returning to the sheets.

6. Sprinkle desired toppings on each bite and bake for 16–20 minutes, rotating halfway, then cool completely on wire racks.
