Make the Dough: Mix flour, salt, and margarine. Add ice water, knead until half-smooth, then rest the dough for 30 minutes.
Prepare the Filling: Sauté garlic and shallots until fragrant. Add carrot and potato with a splash of water. Season with salt, pepper, nutmeg, and mushroom stock. Cook until veggies are tender.
Add the Cheese: Cut Prochiz Mozzarella into 20 small pieces.
Shape the Pastel: Take about 20 g of dough, flatten it, and place it on a pastel mold. Add filling and one piece of mozzarella. Seal tightly.
Fry: Deep fry over medium heat until golden brown and crispy.
Serve hot so the Prochiz Mozzarella melts and stretches perfectly~
