Potato Filling Preparation:

Boil potatoes until soft, mash smoothly, then blend with cheddar, salt, and pepper for a rich filling.

Assembling the Pastry:

Roll out dough into thin sheets, layer with butter, and freeze briefly to solidify. Then, roll out again, cut into squares, add filling, and fold into pastries, sealing the edges.

Baking to Perfection:

Preheat the oven to 190°C (375°F). Arrange pastries on a baking sheet, brush with egg yolk, and bake for 20-25 minutes until golden and crisp.

Ready to Serve:

Cool slightly before serving these irresistible pastries, ideal for snacks, appetizers, or as a delightful side. Enjoy the captivating blend of crunchy pastry with creamy potato-cheese filling.
