3. Take one oily skin and press flat, put in a shortbread.
4. Slowly push up the oil crust to cover the oil pastry. Squeeze the mouth and round it.
5. Roll out a pastry-covered dough into a tongue shape.

11. Pinch the bottom tightly after closing the mouth.
12. After all is done, put it into the bakeware. Press it down slightly.
13. Brush the surface with liquid egg yolk.

15. Put it in the preheated oven, middle level, upper and lower heat, 180 degrees, about 25-30 minutes.

Tips:Don't make the dough of the oily skin too dry, otherwise it will not be malleable when it is wrapped, and it will break easily. The filling can be changed to what you like.
