Before starting this recipe, preheat the oven to 180°C (350°F), grease, and line a baking sheet with parchment paper.
In a large bowl, crumble the feta cheese and add the ricotta and kefalotyri cheeses, followed by the beaten eggs.
200 g feta cheese, 200 g ricotta cheese, 50 g kefalotyri cheese, 2 eggs
Combine the cheese and eggs until well combined.
Place one sheet of phyllo on a clean bench with the longer edge facing you, brush with melted butter, and layer another sheet on top. Proceed until you have a stack of 3 phyllo sheets brushed with butter.
15 sheets fillo pastry, 250 g butter
Cut out 5 vertical strips from the pastry (each should measure approximately 3 inches or 8 centimetres)
Place one heaped tablespoon of the cheese mixture at the base of the sheet, allowing a few cm of space and press down lightly. (note 6)
Fold diagonally to form a triangle, then continue folding, ensuring you keep a triangular shape. (Any excess pastry can be “tucked in” by brushing it with some extra butter). Continue with the remaining phyllo and filling until you end up with 25 pies.
Place the tiropitakia on a baking sheet, brush both sides with butter and bake for 20 minutes or until golden brown.
Remove from the oven and allow them to cool before serving slightly warm or at room temperature.
