Let the dough sheets rest at room temperature for about 10 minutes. Melt butter in a small pot. Grease 4 non-adjacent wells of a muffin tin (12 wells). Remove 2 pastry sheets from the pack. Repack the rest well and place in the fridge. Process in another way as soon as possible. Cut the dough sheets into about 20 rectangles. Spread 5 rectangles with butter on each and place them in a trough. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 10-15 minutes. Take the muffin tray out of the oven, let it rest for about 5 minutes and remove the muffins from the tin
