In a large bowl, whisk together the flour, sugar, and salt. Slowly pour in hot water while using a fork to stir it in. Slowly pour the in the cool water next, still using the fork. You should have what appears to be a very shaggy dough. Using your hands, press the dough together until it starts to form a ball. On a clean work surface lightly dusted with flour, knead the dough for about 3 minutes until a smooth dough forms. Cover the dough and let rest for 30 minutes.

While the dough rests, make the filling by whisking together the melted butter, flour, and salt. Set aside.

Cut the dough into six even pieces, roll them into a ball. Working with one dough ball at a time, keep the other dough balls covered with plastic wrap. On a lightly floured, clean work surface, roll out the dough into a roughly rectangular shape as thin as you can get it. Take one tablespoon of the filling and brush it over the dough, leaving a half-inch barrier all around. Sprinkle with 1/6 of the green onions.

With the long side facing you, begin to roll the dough into a long thin log. Press the seams together on the sides and along the length of the log. Roll into a spiral shape, tucking the edge underneath. Place under the plastic wrap with the other dough balls and continue with the remaining dough.

Preheat your air fryer to 350 degrees F. Take one of the spirals and gently flatten it with the palm of your hand on your clean work surface. Roll it out into a 7 to 8-inch circle.

Spray the basket of the air fryer with olive oil spray. Place the pancake into the basket and spray the top with olive oil. Air fry for 5 minutes, flip, spray again and cook for an additional 5 minutes or until desired crispiness.

Repeat with the remaining dough, cut into triangles if desired, and serve with the dipping sauce of your choice.

Plate, serve, and enjoy!
