First prepare the ingredients, including flour, salt, eggs and water, then mix the flour with salt and eggs, then add water and mix into a liquid batter, and finally add chopped scallions. Put a little bit of oil in a non-stick skillet pan, pour the batter into the pan and cook the pancake, flip it over when one side is non-stick and continue to cook until both sides are golden brown to remove from the pan. Finally, cut the scallion pancake into 4 slices, plate and enjoy.
