Easy No-Yeast Black Bread — No Baking Soda or Starter Needed

Black bread
Ingredients:

300 g of rye flour
180 g of wheat flour
20 g of bran
1.5 tsp of salt
1.5 tbsp of sugar (or honey)
1.5 tbsp of oil
450-500 ml of water

Combine all the ingredients in a 2-liter bowl (I used a pot).
Mix until the dough is uniform using a mixer fitted with dough hooks (about 3-4 minutes).
Cover the pot with a lid and place it in a warm spot for 24 hours (I set mine near the radiator).
Take a 25 cm baking sheet, grease it with oil, and dust it with flour.
Transfer the dough to the baking sheet and set it in a turned-off oven for 1 hour to rise.
Preheat the oven to 150 degrees Celsius (about 300 degrees Fahrenheit) and bake the bread for 1 hour.
Remove the baking sheet from the oven, flip the bread onto a board (or cooling rack), and cool at room temperature for 1 hour to let excess moisture escape and improve the texture.
