In a bowl, mix the flour, salt, and yeast. Add the yogurt and mix by hand until a dough is formed. If the mixture is too dry add 1 or 2 tablespoons more of the yogurt. Form a ball. Line the Instant Pot with parchment paper and place the dough ball inside. Cover with the lid on and press the Yogurt button. Let the dough proof inside the Instant Pot until the timer displays 4 hours. Remove the dough from the Instant Pot and lay on a floured surface. Knead and shape into a ball. Transfer to a piece of floured parchment paper, then cover a large bowl on top and let proof again for 1 ~ 2 hours. 45 minutes before the dough is ready, preheat a dutch pan in the oven at 450 °F for 30 minutes. To bake the bread, lift the parchment paper to transfer the dough into the preheated pot, score the top with a knife and place lid and bake for 25 min. Then remove the lid, and bake for 8-10 more minutes or until browned. Remove from oven and cool on a rack.
