In a mixing bowl, combine the active sourdough starter, warm water, avocado oil, and honey until smooth. Add flour and salt, then cover and let rest for 1 hour.
Perform 4 sets of stretch-and-folds, 30 minutes apart, to develop gluten and create a smooth dough.
Cover and let rise 4–8 hours, or overnight for a long fermentation process. The dough is ready when doubled, bubbly, and airy.
Turn the dough onto a lightly floured work surface and divide into 8 (or 16 if you want more rolls) equal sized dough balls (about 113 grams).
Use the second portion of dough to make into sandwich bread loaf or more rolls.
Shape each roll using a gentle circular motion to build surface tension.
Allow the shaped rolls to rise about 2 hours in a warm place. This step gives you that soft, fluffy texture.
Before baking, brush the top of the rolls with melted butter using a pastry brush for a tender, golden brown crust.
Preheat the oven to 400°F. Bake for 30 minutes, then reduce to 375°F for another 15 minutes, until the internal temperature reaches 205°F.
Remove from the baking pan and cool on a wire rack before serving.
