- 1
In a large bowl, combine 2 cups of rye flour and 1 cup of all-purpose flour.
- 2
Add 1/2 cup of rye starter to the flour mixture along with 1 1/2 cups of water. Stir until a smooth batter forms.
- 3
Cover the bowl with a damp cloth and let it sit at room temperature for 12-24 hours to ferment.
- 4
Once fermented, add 1 teaspoon of salt to the mixture and mix until well combined.
- 5
Transfer the dough to a lightly floured surface and knead for about 5-10 minutes until it becomes elastic.
- 6
Shape the dough into a round loaf and place it in a floured proofing basket or bowl, seam side up. Cover it with a cloth and let it rise for another 3-4 hours at room temperature.
- 7
Preheat your oven to 450°F (230°C) while the dough is rising. Place a Dutch oven or heavy pot inside to heat up.
- 8
Once the dough has risen, carefully turn it out onto a parchment-lined surface. Score the top with a sharp knife.
- 9
Remove the hot pot from the oven and place the parchment with the dough inside. Cover with the lid and bake for 30 minutes.
- 10
After 30 minutes, remove the lid and bake for another 15-20 minutes until the bread is dark brown and sounds hollow when tapped.

Allow the bread to cool completely on a wire rack before slicing.
