Mix the dough: Add flour, salt and garlic powder to a medium bowl. Stir to combine. Add 3/4 cup of hot water to the flour and stir with a wooden spoon. Continue stirring until all the water has been absorbed by the flour. Dont worry if the dough has not formed completely yet.

Knead the dough: Knead all the bits of dough together with your hands inside the bowl. If your dough is still very dry, add a splash of hot water, about 1 to 2 tablespoons, until it comes together and all the flour is absorbed

Continue kneading the dough for about 2 more minutes. The dough will feel moist but it should not stick to your hands too much.

Rest the dough: Shape the dough into a round ball. Cover the bowl with plastic wrap and let the dough rest for 30 minutes.

Roll out the pancakes: Sprinkle flour on top of a work surface. Divide the dough into 4 pieces of equal size. Work with one piece at a time, leaving the remaining pieces in the bowl.

Shape piece of dough into a small ball. Use a rolling pin to roll out the dough into a thin circle, about 7 to 8 inches in diameter.

Add the scallions: Brush a thin layer of canola oil on top of the dough, making sure not to miss the edges. Sprinkle sliced scallions all over the dough.

Roll and flatten the pancake: Starting on one end, roll the circle of dough into a log. Take one end of the rolled up dough and curl it toward the center, like a snails shell. Tuck the end of the dough underneath the spiral.

Use the palm of your hand to flatten the dough into a thick circle. Roll it out again with your rolling pin. Try to roll it out as thinly as possible. A few slices of scallions may pop out during the process, and thats perfectly normal.

Transfer rolled out scallion pancake to a plate. Repeat steps 4 through 6 with the remaining dough pieces.

Cook the pancakes: Heat about 2 teaspoons of canola oil in a small nonstick or cast iron skillet over medium heat. Place one of the pancakes in the middle of the pan and pan fry each side for about 2 to 3 minutes, until golden brown. Transfer to a plate and repeat with the 3 remaining scallion pancakes, adding more oil to the pan as needed.

Prepare the dipping sauce: Mix all the sauce ingredients in a small bowl. Adjust the seasonings to your liking, adding more soy sauce or vinegar, if you like. Add any leftover scallions to the dipping sauce, and add a pinch of red pepper flakes if you would like a bit of spice.

Serve the hot pancakes: Cut the scallion pancakes into small wedges and serve while hot with the dipping sauce. (The pancakes are still good when cooled, but will no longer be crispy.)
