Ingredients:

  • 450 g (3 cups plus 2 Tbsp) Strong White Bread Flour (High-Protein)
  • 60 g (1/2 cup) Whole Wheat Flour (Stone Ground)
  • 4 g (1 tsp) Instant Yeast (or Active Dry)
  • 9 g (1 1/2 tsp) Fine Sea Salt
  • 420 ml (1 3/4 cups) Lukewarm Water (approx. 105°F / 40°C)

Instructions:

  1. Combine Dry Ingredients: In the large mixing bowl, whisk together the flours, instant yeast, and salt. Ensure the salt and yeast are evenly distributed.
  2. Add Water: Pour the lukewarm water into the dry mixture. Using a spatula, mix vigorously until a shaggy, wet, uniform dough forms. There should be no dry pockets of flour left.
  3. Rest (The Bulk Ferment): Cover the bowl tightly with plastic wrap or a lid. Place the dough in a cool, draft-free spot (or the fridge for an extra-long ferment). Allow the dough to rest for 12–18 hours, until it has doubled in size, is visibly bubbly, and smells slightly acidic.
  4. Flour the Surface: Lightly flour your work surface and dust your hands. The dough will be very sticky—don't panic!
  5. Remove Dough: Gently scrape the dough out of the bowl onto the floured surface. Do not punch it down aggressively; try to keep the air structure intact.
  6. Pre-Shape (The Fold): Fold the dough over onto itself (like folding a letter into thirds, then rotating 90 degrees and folding again). This builds initial tension.
  7. Shape: Flip the dough seam-side down and lightly cup your hands around it, dragging the dough across the counter to tighten the outer skin into a neat, round ball (boule).
  8. Second Proof: Transfer the loaf seam-side up into the prepared, heavily-floured banneton basket or towel-lined bowl. Cover loosely. Let proof for 1.5 to 2 hours at room temperature, until slightly puffy.
  9. Preheat the Oven and Dutch Oven: Place the Dutch oven (with the lid on) into the cold oven. Preheat the oven to a scorching 475°F (245°C). Allow 30–45 minutes for the Dutch oven to fully heat.
  10. Prepare Loaf: Carefully remove the piping hot Dutch oven from the oven. Gently invert the dough from the banneton basket onto a piece of parchment paper.
  11. Score: Using a razor blade (lame), make one deep, rapid cut across the top of the loaf (about 1/2 inch / 1.5 cm deep). This guides the 'oven spring'.
  12. Bake Covered: Using the parchment paper like a sling, lower the dough into the hot Dutch oven. Place the lid back on immediately. Bake for 30 minutes covered.
  13. Bake Uncovered: Remove the lid. Lower the temperature slightly to 450°F (230°C). Bake for an additional 15–20 minutes uncovered, until the crust is deep golden brown and sounds hollow when tapped.
  14. Cool Completely: Carefully remove the loaf from the Dutch oven and place it on a wire rack. Allow the loaf to cool completely for at least 1.5 hours before slicing.
