Put a baking pan or cast iron skillet with about 1 tbsp of butter in the preheating oven to heat up. Remove after 5 minutes. In a large mixing bowl, add the self-rising flour and salt, mix well.
Turn dough onto a lightly floured surface; knead lightly just until it forms a nice disc to roll. Press it into a rough rectangle and fold the dough 4 or 5 times onto itself.
