Cut the puff pasty into half and cut two circles. (If you wanna make bigger one, use two sheets of puff pastry) Spread the pesto on one puff pastry, then cover it with another pastry.

Place a cup in the middle, then slice it around it. Twist each ray two times, then lay flat. Brush beaten egg on top, spring some sesame seeds on top. Pop in preheated oven at 200C, bake for 22 to 24 minutes or until crispy.
