Mix flour and salt together in a large bowl.
Make a hollow in the flour with your fist.
Crumble the yeast into the hollow. Fill up with 50 ml water and leave to rest for about 10 minutes.
Add the remaining water and knead well with a food processor for a few minutes. Caution: Since the dough contains rye flour, it is quite sticky. That is normal!
Cover the dough and let it rise at a warm place for about 1 hour.
Form the dough into a round loaf and place it on a baking sheet covered with baking paper.
Let the bread rest for another 10 minutes. In the meantime, preheat the oven to 230 degrees convection air. Sprinkle bread with water and dust it with flour.
Place a small heatproof pan filled with water on the bottom of the oven to generate plenty of steam while baking.
Bake the bread in the middle of the oven for about 40 minutes.
