In a large bowl, combine flour and boiling water, stirring until a dough forms. Knead on a floured surface until smooth. Cover and let rest for 30 minutes.

Divide the dough into four equal parts. Roll each part into a thin circle.

Brush a thin layer of oil on the surface of each circle, sprinkle with salt and chopped scallions, then roll tightly into a log. Coil the log into a spiral and flatten gently with your hand.

Heat oil in a skillet over medium heat. Fry each pancake for 2-3 minutes on each side until golden brown and crispy.
