Crafting the Dough:
Commence by activating the yeast in warm water until fully dissolved. Gradually incorporate the flour and salt, kneading until a soft, elastic dough forms. Divide the dough into 8 portions, cover, and allow it to rest for 25 minutes.
Preparation of Potato Filling:
Boil the potatoes until tender, then mash them to a smooth consistency. Combine with cheddar cheese, salt, and pepper to create a luscious filling.
Assembling the Pastries:
Roll out the dough into thin sheets, generously layer with butter, and briefly freeze to firm up. Once solidified, roll out the dough again, cut into squares, add the filling, and fold into pastries, ensuring the edges are well-sealed.
Baking to Flawless Crispness:
Preheat your oven to 190°C (375°F). Arrange the pastries on a baking sheet, brush with egg yolk, and bake for 20-25 minutes until beautifully golden and crispy.
Ready to Serve:
Allow the pastries to cool slightly before serving, presenting a delightful treat perfect for snacks, appetizers, or as a delightful accompaniment. Savor the delightful contrast of crunchy pastry enveloping a creamy potato-cheese filling.
