  • 10 grams salt

Instructions
 

Feed Your Sourdough Starter

  • 8-12 hours before you plan to prep your loaf:
  • Combine 50g sourdough starter, 50g water, and 50g flour in a jar.
  • Stir until smooth and let it sit at room temperature until it doubles in size and becomes bubbly.
  • Note: You will have more starter than needed for the recipe.

Mixing the Dough

  • In a large bowl, mix 125g active sourdough starter with 325g warm water. Stir until dissolved into a milky mixture.
  • Add 500g flour and 10g salt. Mix until a thick dough forms and no dry pockets remain.
  • Cover the bowl with a kitchen towel or plastic wrap and let it rest for 1 hour.

Stretch and Folds

  • Perform 3-4 sets of stretch and folds, 30 minutes apart:
  • Lift one side of the dough, stretch it upward, and fold it over the center.
  • Rotate the bowl and repeat on all sides.
  • Keep the dough covered between sets.

Bulk Fermentation

  • After the final stretch and fold, cover the dough with a damp kitchen towel or plastic wrap.
  • Let the dough rise at room temperature until it looks bubbly, jiggly, and has increased in size.
  • Bulk fermentation time will vary depending on your environment. Hot and humid climates will speed up the process, while cooler, drier climates may take longer.

Shape and Cold-Proof

  • Flour and Transfer
  • Lightly flour your countertop and transfer the dough onto it. If the dough is sticky, use your hands or a bench scraper to gently guide it.
  • Shape the Dough
  • Flatten the dough into a rectangle, being careful not to tear it.
  • Sprinkle a mix of graham crackers, chocolate, and marshmallows evenly over the rectangle.
  • Fold the Dough
  • Fold one side of the rectangle into the center.
  • Sprinkle more inclusions onto the folded section.
  • Fold the other side over the top, creating layers with the inclusions.
  • Roll into a Burrito Shape
  • Add the remaining inclusions on top of the rectangle.
  • Roll the dough from one short end to the other, forming a log shape.
  • Push and Pull for Tension
  • Gently push the dough ball away from you and pull it back to create a smooth, taut top.
  • Transfer the dough to a floured banneton or towel-lined bowl, seam side up.

Rest and Refrigerate

  • Let the dough sit at room temperature for 30 minutes to an hour.
  • Cover it and refrigerate for 4-24 hours. (Longer cold-proofing enhances the sour flavor and digestibility.)
  • Tip: Cover the dough with a damp towel to prevent drying out in the fridge.

Score and Bake

  • Preheat your oven to 450°F (230°C) with a Dutch oven inside for 30 minutes.
  • Gently flip the dough onto parchment paper, seam side down. Dust the top with flour (Thai rice flour works well).
  • Score the loaf with a knife or scoring tool to allow gases to escape. Add decorative designs if desired.
  • Place the dough in the preheated Dutch oven.
  • Baking Instructions
  • Bake covered for 30 minutes.
  • Remove the lid and bake for an additional 15 minutes.
  • Optional: Add extra marshmallows and chocolate to the scored area during the final 15 minutes for a gooey finish.
  • Tip: Place a cookie sheet on the rack below the Dutch oven to prevent the bottom of the loaf from burning.

Cool and Enjoy!

  • Remove the loaf from the oven and let it cool on a wire rack for at least 1 hour before slicing.
  • For extra flavor, add more graham crackers and chocolate into the scored area while it’s cooling.
  • Tip: If you prefer a softer crust, let the loaf cool for 30 minutes uncovered, then cover it with the Dutch oven lid for the remaining cooling time.
