In another Bowl, combine the Butter and Eggs and set aside
In a large bowl, combine the flour, salt and sugar, make a well at the center and add the yeast and the Egg and Butter mixture and mix together until a soft dough is formed.
Transfer the Dough to a lightly floured surface and knead until it’s smooth and elastic about 10 minutes by hand and about 7 minutes if using a mixer.
Place the Dough inside a very large oiled Bowl (making sure you smear some oil on the surface of the Dough) and leave to rise in a warm place for 1 hour or till doubled in size.
Deflate the dough, and turn it out onto a lightly floured surface. Divide the dough into 16 equal pieces, and form into round balls and place it in the Cast Iron skillet/Pan, then leave it to rise for another 30 minutes.
Place the pan on a low heat and cook for 10 minutes. After 10 minutes flip it to the other side and cook for additional 5 minutes.
