Prepare the syrup: In a saucepan over high heat, combine the sugar, water, glucose, and cinnamon stick. Let the mixture come to a boil, then remove from the heat and set aside to cool.
Melt the butter: Put the butter in cubes, cover with cling film, and transfer to the microwave to melt. Alternatively, melt it in a saucepan.
Prepare the pastry sheets: Roll the pastry sheets and place them on top of the baking tray. Cut off the excess edge. Open them, fold twice, cut into folded strips and place them in a baking tray with the seam facing down. Repeat until the baking tray is full.
Bake: Brush the entire surface with melted butter using a spoon. Transfer to the oven and bake at 150°C for 1½ hours until crispy.
Syrup the kurkubinia: Immediately after removing from the oven, syrup the hot dessert with the cold syrup, allowing it to absorb fully.
Serve: Cut into pieces if needed, place in a serving bowl, and optionally sprinkle with roasted peanuts before serving.
