In a large mixing bowl, combine your sourdough discard with all-purpose flour, minced garlic, olive oil, grated Parmesan cheese, dried herbs (if using), and salt. Stir until a soft dough forms.

Transfer the dough onto a lightly floured surface and knead for about 5 minutes until smooth and elastic.

Divide the dough into small pieces, roll each piece into a long rope, and tie into knots. Arrange on a baking sheet lined with parchment paper.

Cover the knots with a clean towel and let them rest while preheating your oven to 400°F (200°C) for 15-20 minutes.

Once preheated, brush the knots lightly with olive oil and bake for about 15-20 minutes until golden brown.

Let the knots cool on the baking sheet for a few minutes before serving warm or at room temperature.
