In a large bowl, combine the lukewarm water and active sourdough starter, stirring until the starter mostly dissolves. Add the flour and salt, mixing with a spatula or your hand until no dry flour remains. The dough will look shaggy and rough, which is completely normal. Cover and let the dough rest for 30 minutes. This rest, called an autolyse-style rest, allows the flour to fully hydrate and begins gluten development with no kneading.

2️⃣ Stretch and Fold

With damp hands, grab one side of the dough, stretch it upward, and fold it toward the center. Rotate the bowl a quarter turn and repeat on all four sides. Cover and rest for 30 minutes. Repeat this process 3 to 4 times over approximately 2 hours. Each round of stretch and folds builds strength and structure into the dough. By the end, the dough should feel smoother, more elastic, and noticeably more cohesive.

Tip: Wet hands prevent the dough from sticking. Keep a small bowl of water nearby to dip your fingers into as you work.

3️⃣ Let the Dough Ferment

Cover the bowl and leave the dough at room temperature until it becomes airy and noticeably increases in volume, usually another 3 to 6 hours. The exact timing depends on your starter and kitchen temperature. Look for these signs that the dough is ready: it has grown by roughly 50 to 75 percent, the surface looks domed and slightly jiggly, you can see bubbles along the edges or through the side of a clear bowl, and the dough feels light and airy when you gently shake the bowl.

Temperature matters. In a warm kitchen (around 78 to 80°F or 25 to 27°C), fermentation may finish closer to the 6-hour total mark. In a cooler kitchen, it can take 10 hours or longer. Judge the dough, not the clock.

4️⃣ Divide into Mini Boules

Turn the dough onto a lightly floured surface and divide it into 12 equal portions. For consistent results, use a kitchen scale. Each piece should weigh roughly 70 to 75 g. Gently shape each piece into a small, tight ball without squeezing out too much air. To shape, flatten a piece slightly, fold the edges toward the center, flip it seam-side down, and gently drag it across the surface with cupped hands to create surface tension.

5️⃣ Prepare the Cupcake Pan

Lightly grease the cups of a standard 12-cup cupcake pan, or use a well-seasoned nonstick pan. Place one dough ball into each cup, seam-side down. The balls will fill the cups loosely at first and expand as they proof.

6️⃣ Give the Dough a Final Rise

Cover the pan loosely with a clean towel, reusable cover, or lightly oiled plastic wrap, and let the dough rise until the balls look puffy and slightly expanded, about 1 to 2 hours at room temperature. Alternatively, refrigerate overnight after shaping, then allow the dough to warm and become puffy before baking. The cold rest slows fermentation and deepens the tangy flavor.

The poke test: Gently press a floured finger into one roll. If the dent slowly springs back about halfway, the dough is ready. If it springs back immediately, it needs more time. If it does not spring back at all, bake right away.

7️⃣ Preheat the Oven

Preheat your oven to 425°F (220°C). Lightly dust the tops with flour and score each boule with a small, shallow cut using a sharp blade, such as a razor blade, a lame, or a very sharp paring knife. Scoring helps the rolls expand in a controlled way and gives them a pretty, bakery-style look. A simple cross, a single slash, or a small X all work well.

8️⃣ Bake Until Golden

Bake for 20 to 25 minutes, until the mini boules are golden brown and sound hollow when tapped. If needed, rotate the pan halfway through baking for even browning. If your rolls are browning too quickly, tent the pan loosely with foil for the last few minutes.

9️⃣ Cool and Serve

Carefully remove the boules from the pan and let them cool on a wire rack for at least 30 minutes. This resting time lets the crumb finish setting, so the inside is not gummy. Serve warm or at room temperature with butter, cheese, soup, or your favorite spreads. 🧈🧀

💡 Tips for Perfect Mini Sourdough Boules

1. Use an active starter. A bubbly, recently fed starter helps the dough rise reliably. A good test is to drop a spoonful into a glass of water: if it floats, it is likely ready to use.
2. Shape gently but firmly. Creating surface tension helps the mini loaves hold their round shape.
3. Avoid overfilling. Divide the dough evenly so each boule has room to expand and does not spill over the cups.
4. For a crispier crust. Place a separate oven-safe pan of hot water on the lower oven rack during the first 10 minutes of baking, taking care to avoid steam burns.
5. Let them cool before cutting. This helps the crumb finish setting.
6. Weigh your ingredients. Sourdough is sensitive to hydration, so a kitchen scale gives more consistent results than measuring cups.
7. Watch the dough, not the clock. Fermentation times vary widely, and dough that is underproofed or overproofed will not bake as well.
8. Grease generously if unsure. If your pan is not nonstick, a thorough coating of oil or butter prevents the rolls from sticking.
9. Use the fridge for flexibility. A cold overnight proof lets you fit baking into your schedule and adds extra flavor.
