Do I have to use active sourdough starter?
Yes. You want starter that is active and bubbly, ideally used near peak. If your starter is sluggish, the dough can take forever and bake up dense.
My kitchen is cold. How long will the rise take?
Longer than the clock says. Rise times below assume a room temp around 72 to 75°F. For the bulk rise, look for the dough to grow by about 50 to 75% and feel lighter and slightly puffy. In a cool kitchen this can take 6 to 10 hours. A warm spot helps.
Should I let it double?
Not necessarily. Enriched sourdough dough (milk, butter, egg) can be sneaky and may not fully double on the first rise. Go by the cues: puffier, lighter, smoother, and about 50 to 75% larger.
Can I do this overnight?
Absolutely. After you mix and start the bulk rise, chill the dough in the fridge for 8 to 16 hours. Cold fermentation slows things down and boosts flavor. The next day, let the dough sit at room temp for 30 to 60 minutes before shaping if it is very stiff. If your starter is on the weaker side, expect the next day to move a little slower.
Can I refrigerate the rolls after shaping?
Yes, and it is a great make-ahead move. Shape and place in the pan, cover tightly, and refrigerate for 8 to 18 hours. When ready to bake, let them sit at room temp until noticeably puffy (often 2 to 4 hours, longer if your kitchen is cool), then bake as directed.
Why are my rolls not fluffy?
Common culprits: underproofed dough, weak starter, flour measured too heavily, or not enough kneading. The dough should be smooth and elastic, and the shaped rolls should look noticeably puffy before baking. When you press a roll gently, it should leave a slight indentation and spring back slowly.
Can I use all-purpose flour instead of bread flour?
Yes. Bread flour gives a slightly taller, chewier roll. All-purpose still works and stays soft. If using all-purpose, hold back a tablespoon or two of liquid at first and add only if the dough looks dry.
Can I make these dairy-free?
You can swap the milk for unsweetened oat milk and the butter for a plant-based butter. The rolls will still be soft, just a little less rich.
How do I know they are done baking?
They should be deeply golden on top, and the center rolls should read about 190 to 195°F on an instant-read thermometer.
