# Ingredients:
→ Dough Base
01 - 4 cups strong bread flour
02 - 1 1/2 cups lukewarm water
03 - 1/2 cup active sourdough starter or 2 1/4 teaspoons instant yeast
04 - 2 teaspoons fine sea salt
05 - 1 tablespoon olive oil
→ Fibonacci Spiral Additions
06 - 2 tablespoons toasted sunflower seeds
07 - 1/4 cup chopped walnuts
08 - 1/3 cup pumpkin seeds
09 - 1/3 cup grated hard cheese (Gruyère or Parmesan)
10 - 1/4 cup chopped sun-dried tomatoes, drained
11 - 1/3 cup mixed olives, pitted and chopped
12 - 1/3 cup sautéed spinach, well-drained
# Instructions:
01 - Combine flour and lukewarm water in a large mixing bowl. Stir until just combined. Cover and let rest for 30 minutes.
02 - Add sourdough starter or yeast, salt, and olive oil to the mixture. Stir and knead on a lightly floured surface for 8 to 10 minutes until the dough is smooth and elastic.
03 - Place the dough in a lightly oiled bowl. Cover and let it rise at room temperature for 8 to 12 hours until doubled in size.
04 - Turn the risen dough onto a lightly floured surface and divide it into seven equal portions.
05 - Knead each portion with the spiral additions, starting from the smallest quantity (sunflower seeds) and increasing with each subsequent portion, ending with sautéed spinach in the largest piece.
06 - Roll each portion into a rope. Coil the ropes concentrically on a parchment-lined baking sheet, sealing the ends to form a continuous spiral.
07 - Cover loosely and allow the shaped dough to rise for 1 hour and 30 minutes until puffy.
08 - Preheat the oven to 445°F (230°C). Place an empty tray on the oven floor for steam generation.
09 - Dust the loaf lightly with flour and score spiral lines with a sharp blade to facilitate expansion during baking.
10 - Pour one cup of hot water into the preheated tray to create steam. Bake the loaf for 40 minutes, rotating halfway through, until the crust is golden brown and crisp.
11 - Transfer the bread to a wire rack and allow it to cool completely before slicing.
