Dust the working surface with a thin layer of flour, roll the dough out to an approximately 10" x 16" rectangle.
Spread the oil paste by spatula or by hand on the dough, leaving ½ inch on the top.
Roll the dough from the bottom all the way up, pinching the seam at the end to close.
Cut the roll into 6 even pieces and gently press each piece down to flatten a bit and bring the two "cut" sides to the middle and pinch them together (it's ok if they don't stay together perfectly).
Gently roll each piece out to an oval shape and then fold the top third of the dough down and the bottom third up. After finishing all six pieces, repeat this step again for each piece. Always fold the side with oil paste in so that we'd end up with a smooth surface. Cover and let rest for 10 minutes.
Put sesame seeds in a small plate and lightly press the smooth side of each piece of dough into the plate of sesame seeds.
