Set up a food processor and combine the All-Purpose Flour (1 cup), Salt (1 teaspoon) and Baking Powder (1/2 teaspoon) in its bowl. Pulse it a couple of times to aerate the dry ingredients.
Run the processor while you pour the Water (1/2 cup) in until you have a sticky dough form.
Turn the dough out onto a lightly floured and clean surface and bring it together into a smooth ball.
Transfer the ball of dough to a bowl and pour the Sesame Oil (2 tablespoon) over it. Make sure it is all coated in the sesame oil, then cover it and let it rest for an hour.
When it is done resting, roll it out into a large rectangle that is about 1/4 inch thick. Sprinkle enough of the Scallion (1 bunch) on the rectangle to pretty well cover it in a single layer.
Roll up the long side of the rectangle tightly over the scallions so that you have a long log. Take the log and roll it tightly into a spiral that looks like a snail shell. Roll out the snail shell to be a thin round pancake.
Then heat about 2 inches of Canola Oil (to taste) in a large skillet over medium high heat.
Once the oil is hot, pan fry the scallion bread for 3-4 minutes on each side to get it golden brown and crispy on the outside. It will puff up and the interior needs to cook too.
When it is done, transfer it to a plate lined with a paper towel to drain it. Then cut it into quarters and serve it immediately with a delicious Chinese meal! Enjoy!
