Combine flour, rice flour, and sea salt in large bowl and stir together.
2 cups gluten free all-purpose flour, 1/2 cup rice flour, 3/4 tsp sea salt
Add boiling water and stir with a spoon until everything comes together. Use your hand to knead until a dough forms. If it's too dry add a little bit more water and continue kneading until smooth.
1 cup boiling water
Divide the dough into 6 equal pieces. Keep them covered with a damp towel while you work so they don't dry out.
Take 1 piece and place between two parchment paper. Use a rolling pin to flatten it out to a thin rectangle.
Brush on a layer of sesame oil, then add 1/4 cup of chopped scallion in an even layer - leaving about an inch of space empty on one of the longer sides.
1 tbsp sesame oil
Slowly roll up from the longer filled up side to the empty side into a log. Take one end of the log and roll it up towards to the other side into a pinwheel circle. It's okay if the dough breaks a bit while you do this - just try to place the scallions back in the dough.
Place the pinwheel circle in between two parchment paper and use a heavy circular plate or a pot to flatten it out. Use a rolling pin to flatten it out even more to a circle that's about 7-8 inches in diameter (the thinner the pancake, the crispier it'll get).
Repeat with the rest of the dough pieces.
Heat a thin layer of oil in a large skillet over medium heat.
Avocado oil
Add a pancake to the pan and cook for 3-4 minutes until crisp and browned on the bottom. Flip, add more oil to the sides, then tilt the pan so the oil can spread out through the bottom. Cook for 3-4 more minutes until crispy.
Transfer to a cooling rack or a cutting board while you cook the rest of the pancakes.
Stir dipping sauce ingredients in a small bowl and serve with the warm pancakes. I like to cut each pancake in to 6 or 8 triangles.
2 tbsp tamari sauce, 1½ tbsp rice vinegar, 1/2 tsp sugar
