Method

1. 1 Knead the dough with cold water for 12 minutes, then let it rest for 40 minutes.
2. 2 Roll the dough very thinly, then brush with oil, sprinkle with salt and green onions, and roll and twist into a spiral shape.
3. 3 Roll it out into a thin disc only 4 mm thick, thinner than the thicker pan-fried version, so the whole pancake is crispy instead of soft in the middle.
4. 4 Sprinkle roasted sesame seeds on one side and press gently so the seeds stick.
5. 5 Fry in a pan with plenty of oil for 3 minutes on each side, pressing down repeatedly with a spatula.
6. 6 Flattening the pastry while frying ensures even crispiness; failing to flatten it results in a puffy center with remaining dough.

With an appliance

• Air fryer 59 min

  Replace steps 5 and 6: spray oil evenly on both sides of the thin pancake, fry in an air fryer at 195 degrees for 9 minutes, flip at the 5th minute and press flat with a wire rack to ensure even crispiness.
