# What You Need:
→ Sourdough Starter
01 - 1/2 cup active sourdough starter, fed and bubbly
→ Dough
02 - 2.5 cups bread flour
03 - 1/3 cup whole wheat flour
04 - 1 cup water, room temperature
05 - 1.5 teaspoons fine sea salt
→ Decoration
06 - Rice flour for dusting
07 - Edible dried flowers or seeds for garnish, optional
# Step-by-Step:
01 - In a large bowl, mix the sourdough starter, bread flour, whole wheat flour, and water until combined. Let rest uncovered for 30 to 45 minutes to allow flour hydration.
02 - Add salt and mix thoroughly until well incorporated into the dough using a dough scraper or hands.
03 - Perform 3 to 4 sets of stretch-and-folds, spaced 30 minutes apart. Cover the dough with a damp towel between sets to retain moisture.
04 - After the final fold, shape the dough into a tight ball. Place in a lightly oiled bowl and let rise until doubled in volume, 4 to 6 hours at room temperature.
05 - Turn the dough onto a lightly floured surface and divide in half. Shape each piece into a heart by flattening slightly, pinching the base to form a point, and creating an indent at the top center.
06 - Place each heart-shaped dough into a floured proofing basket or bowl lined with a floured towel. Cover and refrigerate overnight for 8 to 12 hours for cold proofing.
07 - Preheat oven to 465°F with a Dutch oven or baking stone inside for at least 30 minutes.
08 - Remove dough from refrigerator. Invert onto parchment paper, dust generously with rice flour, and use a sharp blade to score artistic heart patterns into the surface.
09 - Transfer to the hot Dutch oven or baking stone. Bake covered for 20 minutes, then uncover and bake for an additional 15 minutes until golden brown and crisp.
10 - Cool completely on a wire rack for at least 2 hours before slicing. Decorate with optional edible flowers or seeds as desired.
