In a large bowl, whisk the flour, cornstarch, and salt together.
Add the oil and water then whisk again until no lumps remain.
Grease a flat pan or skillet with oil and place over medium-high heat.
Pour the batter into a pastry bag and cut a very small hole in the tip.
Pipe the batter onto the pan by moving it back and forth creating zig-zags.
Remove the dough with a spatula once the batter starts to peel away from the pan.
Repeat steps 4 and 5 until all of the batter is used.
Bake or toast the dough to fully cook it before serving.
