Mix dry ingredients: In a large bowl, combine 4 cups of flour, 1 large spoon of sugar, 1 large spoon of yeast, and 1 small spoon of salt. Mix well.
Add wet ingredients and knead: Add 1 cup of slightly warm water and 1/2 cup of buttermilk or yogurt to the dry mix. Knead well until the dough becomes soft and smooth.
Add oil and knead again: Add 2 spoons of oil and knead thoroughly until the dough is cohesive and does not stick to your hands.
First fermentation: Lightly grease a fermentation dish with oil. Place the dough inside, cover it, and leave it to ferment until it doubles in size.
Divide dough into balls: Once doubled, remove the dough and cut it into small balls about the size of a large lemon. Sprinkle flour to prevent sticking.
Roll and fold dough balls: Take each ball, sprinkle with flour, and roll into a circle of medium thickness. Brush melted butter on the surface and fold in half. Repeat for all balls.
Second fermentation: Arrange the folded dough pieces and cover them again. Let them ferment for another half an hour.
Prepare for cooking: Brush the top of the dough with egg or cream, then sprinkle coarse breadcrumbs for a crunchy crust.
Cook the bread: You can either fry the bread in a pan with a little oil on high heat, turning to brown both sides, or bake it in a very hot oven until golden and cooked through.
Serve with fillings: Once cooked, open the bread and fill with your choice of fillings such as white cheese and tomatoes, cheddar cheese, turkey, minced meat, eggs and sausage, or any preferred fillings.
