Step 1

Place flour in bowl of food processor (see note). With processor running, slowly drizzle in about 3/4 of boiling water. Process for 15 seconds. If dough does not come together and ride around the blade, drizzle in more water a tablespoon at a time until it just comes together. Transfer to a floured work surface and knead a few times to form a smooth ball. Transfer to a bowl, cover with a damp towel or plastic wrap, and allow to rest for 30 minutes at room temperature, or up to overnight in the fridge.

Step 2

Divide dough into four even pieces and roll each into a smooth ball. Working one ball at a time, roll out into a disk roughly 8-inches in diameter on a lightly floured surface. Using a pastry brush, paint a very thin layer of sesame oil over the top of the disk. Roll disk up like a jelly roll, then twist roll into a tight spiral, tucking the end underneath. Flatten gently with your hand, then re-roll into an 8-inch disk.

Step 3

Paint with another layer of sesame oil, sprinkle with 1/2 cup scallions, and roll up like a jelly roll again. Twist into a spiral, flatten gently, and re-roll into a 7-inch disk. Repeat steps two and three with remaining pancakes.

Step 4

Combine all the sauce ingredients and set aside at room temperature.

Step 5

Heat oil in an 8-inch nonstick or cast-iron over medium-high heat until shimmering and carefully slip pancake into the hot oil. Cook, shaking the pan gently until first side is an even golden brown, about 2 minutes. Carefully flip with a spatula or tongs (be careful not to splash the oil), and continue to cook, shaking pan gently, until second side is even golden brown, about 2 minutes longer. Transfer to a paper towel-lined plate to drain. Season with salt, cut into 6 wedges. Serve immediately with sauce for dipping. Repeat with remaining 3 pancakes.
