Method
Make the Levain
- 25g active starter,50g water, and 50g flour.Mix active starter, water, and flour in a small jar.Cover with plastic wrap or a lid and let it ferment at room temperature for 4–6 hours or until bubbly.Use 120g in the dough.
Mix the Dough
- In a large bowl, whisk the levain (active sourdough starter) into the water using a dough whisk until dissolved. Then add the four and salt, mix until fully incorporated. The dough will look shaggy. Cover with a damp tea towel or plastic wrap and rest for 1 hour.
Stretch & Fold With Butter
- You’ll perform three sets of stretch-and-folds, one each hour. The main thing: keep the butter cold so it forms layers instead of melting.
First Fold- Sprinkle in half of the grated cold butter. Grab one side of the dough then slowly stretch it up, fold it over to the middle, then turn the bowl a quarter and repeat the process till you went all around.
Second Fold- Add the remaining butter. Fold again to create more layers.
Third Stretch (Final Fold) — Add the Chocolate- Sprinkle chocolate chips across the top of the dough. Gently fold so they distribute without tearing. This gives the “au chocolat” croissant effect.
Let the dough rest 3 hours.
Shape & Cold Ferment
- Lightly flour a work surface. Gently shape the dough into a round, rest 15 minutes, then do the final shaping using the letter fold.Place into a floured banneton, seam side up.Cover and refrigerate (cold fermentation) 8–16 hours.Chilled dough is easier to score and creates more distinct buttery layers.
Bake
- Preheat your oven to 475°F with a Dutch oven inside.Transfer the chilled dough onto a piece of parchment paper or a bread sling. Score the loaf, then bake:Cool on a wire rack.40 minutes covered, then, 5–10 minutes uncovered until deep golden brown
