Divide the dough into 4 portions.
For each of the dough, make a bowl shape, and place the “puff pastry” into the dough, and seal it. Repeat for 4 times.
Use a rolling pin, press it against the dough to produce a flat layer.
Roll up the thin layer and cut it in half.
Repeat the process 4 times; you should have 8 dough pieces now.
To produce a beautiful layering effect, again, use a rolling pin, to get a flat layer.
Now, wrap one red bean ball within the flat layer and seal it. Press it gently.
In a small bowl, add 1 cup of water and 1 tbsp of flour and mix it gently.
Brush the mixture onto the dough surface (from step 7) before sprinkling the white sesame seeds.
Flip the dough and repeat the same process (step 9) for another surface.
