Pre-heat oven to 350F.
In a bowl, transfer the self-rising flour followed by the plain greek yogurt and salt (if using additional). Using a sturdy spoon, mix until it starts to come together then use your hands to further gather the mixture to form into a dough. Transfer in a floured surface and lightly gather then divide into 3 or 4 portions. Shape each piece into a ball the slightly flatten it. If the dough is too wet, add a bit of flour or if it is too dry, add a bit more yogurt. Start with 1/2 – 1 teaspoon addition and knead before adding more.
Make a cut on top of each bread, about 1/4-inch deep. This will help in the even baking of the inside of the bread since this is quite a heavy compact bread. Arrange in a baking sheet lined with parchment paper.
Brush top with egg wash (optional). Alternatively, you can brush top with milk or simply dust the top with more flour. Use a sieve for even dusting.
Bake at 350F for about 22 – 25 minutes or until the top is golden brown.
Brush top with butter as soon as you take it out from the oven. Although optional, it is strongly recommended for added taste.
Let cool completely before serving
