For the bread dough:
Weigh in the flour in a large bowl and mix. Add the other ingredients and mix well until the dough no longer sticks to your hands. Otherwise, add a little more wheat flour until the stickiness goes off your fingers and the dough becomes a smooth lump.
Lightly flour the outside of the dough and cover and leave to rest in a warm place for 1 - 2 hours.
Do not knead vigorously after the rest period so as not to destroy the fluffiness.
Carefully shape the bread from the dough and score with a knife. You can also bake 2 smaller loaves of it.
Preheat the oven to 250 ° C, place a casserole dish filled with water on the bottom of the oven and let the oven evaporate.
Then slide the bread into the middle rack and bake for about 20 minutes. Then take out the baking dish, turn the oven down to 230 ° C and bake for another 15-20 minutes until the bread looks nice and crispy.
The Boss Kitchen editorial staff oversees content review, fact-checking, and recipe verification across the site. Published articles pass through the editorial team before going live, ensuring ingredient lists, techniques, cooking times, and nutritional claims hold up in a home kitchen. The team coordinates contributions across the site writers, handles reader corrections, and maintains consistency in measurement conventions, safety guidance, and dietary labeling. Posts under this byline typically represent team-reviewed reference material, site announcements, or editorial roundups rather than individual-author features, and they are held to the same sourcing standards as bylined recipe and product coverage.
