In a large mixing bowl, combine rye flour, all-purpose flour, yeast, carraway seeds, water and salt. Stir in warm water and stir until all ingredients are well combined, and sticky dough forms it’s well combined. Cover with a clean towel or plastic wrap and let the dough rest at room temperature for 3 hours.
1 cup (125 g) rye flour, 2 cups (240 g) all-purpose flour, ½ teaspoon (2 g) dry yeast, 2 teaspoons (12 g) salt, 1 teaspoon (12 g) carraway seeds, 1 ⅔ cup (395 ml) warm water
Transfer the dough onto a clean and floured surface. Also sprinkle a little bit of all-purpose flour on the dough. Use a dough scraper to fold the dough over itself a few times, then shape it into a ball. If the dough is too sticky, add more all-purpose flour.
In another clean and large kitchen bowl, place parchment paper and transfer the bread dough to the kitchen bowl. Cover with a clean kitchen towel and let the dough rise another 20 minutes.
Meanwhile, preheat your oven to 450 °F (230 °C) and place a Dutch oven with a lid in the oven and let it preheat for 30 minutes.
Carefully remove the preheated Dutch oven from the oven and remove the lid. Place the dough with the parchment paper into the Dutch oven and cover it with the lid.
Bake the bread for 35 minutes covered, then remove the lid and continue baking for an additional 15 minutes, or until the crust is dark and crusty.
Remove the Dutch oven from the oven and use oven mitts to remove the bread from the pot. Place the bread on a wire rack to cool. Allow the bread to cool completely before slicing and serving.
