In a medium bowl add flour, ¼ teaspoon salt and gradually add warm water ( tablespoon or so) and mix until it dough pulls away from the sides.Alternatively you can do it in food processor.
Knead the dough for about 15 minutes and make it smooth and cover with damp kitchen towel and set aside for about 20 minutes.
While dough is resting make the dipping sauce, combine all the ingredients for sauce in a bowl and mix well and set aside. You can make the sauce one ahead too.
After 20 minutes in well floured table divide the dough into two equal sized balls. while you are working with one ball of dough make sure to cover the other dough to prevent from sticking.
Roll the dough into a thin circle for about ⅙ inch thickness. Brush the dough with a teaspoon of oil ( you can skip this step if you want) . Sprinkle salt evenly all of the pancake.
Sprinkle ½ cup green onion/scallions all over the pancake. Roll the pancake from one end like rug and seem the ends.
Cut the rolled pancakes into 11 two to three inch pieces. Then spread each pieces into small 5 inch disc. Dust with flour if you find they are sticking to the rolling pen.
Alternatively you make a disc of 5 inch and then spread green onion and salt on it and then roll it into a circle and sprad once again.
Heat 3 tablespoon of oil in a skillet to medium heat, and add 4 pancake cook for about 2 minutes on one side or when they started getting brown spots flip the other side and cook for about another two minutes. Make sure to continuously press the dough for uniform cooking.
Continue to fry the pancake until you finish the entire dough. Add oil if needed.
Remove from the heat and cut into wedges ( I didn't do that part) enjoy with dipping sauce.
