Begin by washing and drying your green onions. Chop them into 1.5-inch pieces, then set them aside.

In a large bowl, combine the chopped green onions, all-purpose flour, potato starch, baking powder, salt, and optional seasonings. Slowly pour in very cold water and stir gently until just combined.

Preheat a non-stick frying pan over medium-high heat, adding enough vegetable oil to coat the bottom.

Pour in half of the batter, spreading it to create an 8-inch circle. Fry for about 3 minutes until golden brown.

Flip the pancake carefully and cook the other side for another 2-3 minutes until golden brown and crispy.

Transfer the pancake to a cutting board, cool slightly, and slice into wedges. Serve warm with your favorite dipping sauce.
