Mix Dry Ingredients: In a large mixing bowl, combine 400 grams of flour, 1 teaspoon of baking soda, ½ teaspoon of baking powder, 1 teaspoon of salt, and 1 teaspoon of sugar. Stir well to ensure that all the dry ingredients are evenly distributed.

Combine Wet Ingredients: In a separate bowl, mix 300 ml of water, 1 tablespoon of vegetable oil, and 1 tablespoon of vinegar (6-9%). Stir until the oil and vinegar are well incorporated.

Add the Wet to the Dry: Slowly pour the wet ingredients into the bowl of dry ingredients. Use a spatula or wooden spoon to mix everything together. The dough will be sticky, but this is normal.

Optional Fillings: At this stage, you can add any optional fillings like seeds (sunflower, flax, sesame) or spices (such as herbs, garlic powder, or caraway). This step is optional but can add extra flavor and texture to your bread.

Form the Dough: Once the dough comes together, transfer it to a lightly floured surface. Sprinkle some flour over the top of the dough to make it easier to handle, and gently shape it into a round loaf. There is no need to knead the dough—just form it into your desired shape.

Prepare the Baking Sheet: Line a baking sheet with parchment paper or lightly grease it with oil. Place the shaped dough onto the prepared baking sheet.

Preheat the Oven: Preheat your oven to 180°C (350°F) while you prepare the dough.

Bake: Place the baking sheet with the dough into the preheated oven. Bake the bread for approximately 40 minutes, or until a golden-brown crust forms. To check for doneness, insert a toothpick or a wooden skewer into the center of the loaf—it should come out clean.

Cool the Bread: Once baked, remove the bread from the oven and transfer it to a wire rack to cool. Let it cool completely before slicing to avoid a doughy texture.
