Make the Dough
Mix flour, salt, warm water, and oil until a rough dough forms. Knead eight to ten minutes until smooth and elastic. Shape into a ball, lightly oil, cover, and rest thirty minutes.
Prepare the Filling
Use any jam or compote. If it is runny, warm gently to thicken and let it cool.
Stretch the Dough
Place dough on a floured towel and stretch it slowly with your fingers and knuckles until very thin. Brush with melted butter if you like.
Fill and Shape
Place a line of filling along one edge, roll or fold the dough over it, and cut into rectangles. Seal the edges with your fingers or a fork.
Bake
Heat oven to 200 degrees Celsius. Place pastries on a parchment lined tray and bake fifteen to twenty minutes until golden.
Glaze (Optional)
Whisk powdered sugar, milk, and vanilla until smooth and drizzle over warm pastries.
