Ingredients

Adjust servings:

Starter Feed

  • 50 g Existing sourdough starter
  • 50 g All-purpose flour
  • 50 g Filtered water

Dough

  • 400 g Water
  • 120 g Active sourdough starter
  • 12 g Fine sea salt
  • 500 g All-purpose flour

Instructions

  1. 1

    Activate Starter: Ensure your sourdough starter has been recently fed and is active/bubbly before you begin.

  2. 2

    Combine Ingredients: In a large bowl, whisk the active starter into 360g of water until roughly dissolved and then add salt and whisk again.

  3. 3

    Add flour: Add the all-purpose flour to the wet mixture. Use your hands or a dough whisk to mix everything until a shaggy, rough dough forms and no dry bits of flour remain. Avoid vigorous kneading; gentle mixing is enough.

  4. 4

    Autolyse/Rest: Cover the bowl with a damp towel or plastic wrap and let it rest for 30 minutes to 1 hour.

  5. 5

    Bulk Fermentation (with gentle folds): Over the next 3-4 hours, perform a few sets of "stretch and folds" every 30-60 minutes to build strength.

  6. 6

    Cold Proof: After the last stretch and folds, cover and place in the refrigerator for 12-15 hours (overnight).

  7. 7

    Preshape: The next morning, gently dump the dough onto a lightly floured surface. Divide into 2 or 3 equal pieces. Gently fold the edges to create a light log shape. Cover and let them rest for about 30–45 minutes

  8. 8

    Shaping: Flip a log over. Fold the top down to the center and press. Fold the bottom up to the center. Fold it in half again, sealing the edge with your thumb, creating a tight log. Gently roll it out to your desired length. Place them seam-side up on a floured couche (linen towel) or parchment paper for the final rise (1–2 hours).

  9. 9

    Preheat: Preheat your oven to 500°F (260°C) with a heavy baking sheet or pizza stone inside. Place a separate metal tray (like a cast-iron skillet) on the bottom rack.

  10. 10

    Prepare: Transfer baguettes to parchment, score with 3-4 quick, shallow, diagonal cuts using a razor

  11. 11

    Score: Using a sharp knife or razor, make a swift cut on top of the loaf to allow it to expand.

  12. 12

    Bake & Steam: Slide onto the hot stone. Immediately dump 1 cup of boiling water into the bottom pan to create steam. Lower temperature to 450°F (232°C).

  13. 13

    Bake for 20 minutes at 450°F (after an initial high heat burst if you prefer). The steam will help the bread rise.

  14. 14

    Remove the steam pan/water tray (be very careful, it's hot!).

  15. 15

    Bake for an additional 25-30 minutes or until the crust is golden brown and sounds hollow when tapped on the bottom.

  16. 16

    Cool: Transfer the finished loaf to a wire rack and let it cool completely for at least 1-2 hours before slicing. This is crucial for the internal structure and to ensure the best texture.

Baker's Tips

  • •Use a lame or sharp razor blade for scoring — a serrated knife will drag.
  • •Let the bread cool completely on a wire rack before slicing for the best crumb.
  • •The float test: drop a small piece of starter in water — if it floats, it's ready.
