In a large mixing bowl, combine the all-purpose flour and salt. Carefully pour in the boiling water, using chopsticks or a fork to stir until a shaggy dough forms. Be cautious of the steam.
When the dough cools enough to handle, transfer it to a lightly floured surface. Knead the dough for about 5-7 minutes until it becomes smooth and elastic. Once ready, cover the dough with a kitchen towel and let it rest for 30 minutes to relax.
After the resting period, divide the dough into four equal pieces. Take one piece and on a lightly floured surface, roll it out into a thin circle, approximately 8-10 inches in diameter.
Using a brush, apply a thin layer of sesame oil over the surface of the rolled-out dough. Generously sprinkle the finely chopped scallions evenly across the dough.
Starting from one edge, carefully roll the dough tightly into a log. Then, coil the log into a snail-like shape, tucking the end underneath. Flatten the coiled dough gently with the palm of your hand.
Roll the coiled dough into another thin circle, aiming for about 1/4 inch thick. Repeat the rolling, oiling, and coiling process with the remaining dough pieces.
Heat a non-stick skillet over medium-high heat and add a tablespoon of the reserved sesame oil. Place one of the pancakes in the skillet and cook for about 3-4 minutes on each side, until it achieves a golden brown hue and crispy texture.
Once cooked, transfer the pancake to a plate lined with paper towels to absorb excess oil. Continue cooking the remaining pancakes, adding more oil to the skillet as needed.
Slice each pancake into wedges. Serve them hot, and if desired, garnish with black sesame seeds for an extra touch of flavor and visual appeal.
Notes
Arrange the scallion pancakes on a rustic wooden board and offer a small dish of soy sauce or a spicy dipping sauce alongside them to enhance the dining experience.
