Thaw the puff pastry in the fridge overnight, until pliable but still cold.
Refrigerator
💡Work with store-bought dough while it's cold: warm puff pastry gets sticky and won't puff in the oven, and phyllo sheets dry out fast, so keep the waiting sheets covered with a damp towel.

Add the mushrooms and thyme and fry, until the liquid evaporates. Let cool.
⚙ Adding to the hot fat and fryingStove
💡Wet vegetables make the dough soggy from the inside: fry or squeeze the spinach until no liquid is left, and cool before mixing with the cheese.
💡Add by cooking time: what needs long (onion, carrot, meat) goes in first, and what burns fast (garlic, dry spices) goes in last, only until fragrant.
4
In a bowl, mix the mushrooms, yellow cheese and eggs, and season with salt and black pepper.

5
Roll out the dough on a work surface and cut into into squares of about 10 cm.

6
Place a spoonful of cooled filling in the center of each piece, fold into a triangle and seal the edges well with a fork.
💡Seal well and press with a fork all along the edges, and don't overfill: a pastry that opens in the oven loses its filling, and in the fryer it fills with oil.
7
Arrange on a baking sheet lined with parchment paper, brush with beaten egg.

💡Brush with an egg beaten with a teaspoon of water: the glaze turns shiny and golden.
8
Bake in an oven preheated to 180°C (355°F) 20–25 minutes, until the pastries are puffed and golden underneath too.

💡Check by the cue (until…), not just the clock: every oven bakes a little differently.
