In a large mixing bowl, combine the flour, yogurt or buttermilk, and water. Stir until a shaggy dough forms.
If desired, add instant yeast and honey or sugar to enhance the rise and flavor. Mix well.
Sprinkle salt evenly over the dough and incorporate it thoroughly.
Cover the bowl with a clean kitchen towel or plastic wrap and let it rest for 2-3 hours at room temperature. This allows the fermentation process to take place.
Preheat your oven to 450°F (230°C) and place a Dutch oven or oven-safe pot with a lid inside to heat up.
Once the dough has risen and developed small bubbles on the surface, gently shape it into a round or oval loaf on a well-floured surface.
Carefully transfer the shaped dough into the preheated pot. Cover with the lid and bake for 30 minutes.
Remove the lid and bake for an additional 15-20 minutes until the bread is golden brown and sounds hollow when tapped on the bottom.
Allow the bread to cool on a wire rack before slicing.
