Combine flour and salt in a bowl, slowly add water in small batches mixing in between.
Knead for a minute, then cover with cling wrap or tea towel and rest for 10 minutes.
Divide dough into 2 pieces. Roll out dough thinly into a rectangle, brush on 1tsp of sesame oil and add scallions. Start to roll it up starting from the wide end so you have a long roll. Coil it into a snail shape, push down with your hand and roll into a round pancake. Repeat with the other ball of dough.
Heat 1 tbsp oil in pan, pan fry for 1 1/2 minutes on the first side, then 1 minute on the other side, pushing down with a spatula if necessary to get it to cook the surface evenly. It should be a dark golden brown. Serve with dipping sauce and enjoy!
