Combine: Place flour, salt, yeast, and flaxseed in the stand mixer (or into a large bowl) and mix for a few seconds. If using instant yeast, mix it with the flour as well (Note 2).300 g all purpose flour/ 2½ cups + 100 g whole wheat flour/ 1 cup + 1 tablespoon + 2 teaspoons fine sea salt + 3 tablespoons flaxseed + 1 package instant yeast Knead: Add lukewarm water, honey, and yogurt and knead with the hook attachments for about 3 minutes or until the dough is elastic and not too sticky. Transfer the dough to the lightly floured working surface and knead shortly, just enough to give it a roughly round shape.175 ml lukewarm water/ ¾ cup + 1 teaspoon honey + 150 g yogurt/ ½ cup + 1 tablespoon Let rise: Place the dough into a bowl, dust with a bit of flour, cover with a clean kitchen towel and let rise until about doubled in size; it will take about 1 hour, depending on the temperature in your kitchen.
Second rise: Turn the bread onto the working surface and knead again shortly. Place a piece of parchment paper on the working surface and place the rounded dough on it. Cover with the towel again and leave it to rise again on the counter while preheating the oven.
Preheat: Place the Dutch oven and the lid in the oven. Turn on the oven and preheat it, and the form to 230°C/ 450°F.
Transfer dough: To place the dough into the pot, carefully grab the sides of the parchment paper and drop the dough together with the paper into the hot Dutch oven. Wear mitts; the dish is extremely hot! Cover it with the lid and place it in the oven.
Bake for 25 minutes with the lid on. Remove the lid and continue baking for about 10-15 minutes or until golden brown.
Check: To make sure that the bread is properly baked, remove it from the pot and tap it with your knuckles; it should sound hollow. Let cool entirely on a wire rack.
