Ingredients

• 3.5 cups white bread flour
• 0.5 cups sprouted spelt flour
• 0.25 teaspoons active dry yeast
• 2 cups cold water
• 1.5 teaspoons fine kosher salt

Instructions

1. 1 Place bread flour, spelt flour, and yeast into a large mixing bowl and stir with a wooden spoon. Pour in cold water and mix until a very wet, sticky dough comes together, about 3 minutes. Add salt and mix for another 2 to 3 minutes. Scrape down the sides of the bowl, cover with foil, and allow dough to rise at room temperature for 18 hours.
2. 2 Deflate bubbly dough with a spatula by scraping down the sides of the bowl and folding dough over itself, turning the bowl as you go around in a circular motion, about 12 times or so.
3. 3 Scrape dough out onto a heavily floured surface. Sprinkle the surface of dough generously with flour. Use floured hands to roll and fold dough on the table into a round or oval shape with a smooth surface, 1 to 2 minutes, adding more flour if dough is too sticky. The loaf shape doesn't really matter, but a smooth surface is the goal.
4. 4 Transfer to a Silpat-lined baking sheet and let rise, uncovered, until doubled in size, about 2 hours. The dough will spread out more than rise up; this is normal.
5. 5 Preheat the oven to 450 degrees F (230 degrees C). Place a rack in the center of the oven.
6. 6 Use a very sharp knife or razor to cut a shallow slash down the middle of dough, being careful not to deflate dough too much; the slash is optional. Spray the surface of loaf very lightly with water to help a crust form.
7. 7 Bake on the center rack in the preheated oven until nicely browned and loaf sounds hollow when tapped, about 30 minutes. Let cool on a wire rack before slicing.
