Steam potatoes beforehand and refrigerate for 2-3 hours or overnight (if you cannot refrigerate your potatoes, you may need more flour to achieve the right dough texture).
Place the steamed potatoes, cassava flour, onion powder, garlic powder, and cilantro (if using) into the food processor.
Let the food processor run until a dough ball forms.
Separate the dough into four equal pieces.
Dust some cassava flour onto the surface you are rolling on, and roll each piece into an oval-shaped flatbread about ¼ inch (or slightly more) thick.
Turn your cooking surface to medium heat and heat your pancake pan until the pan is warm to the touch.
Place your rolled flatbread on the hot pancake pan and cook until the bottom is golden brown. Using a wooden spatula, flip the flatbread over.
Cook the second side the same as the first. If the flatbread puffs up, this is a good sign!
Once cooked on both sides, take off the heat, cool briefly, and enjoy!
Notes
Store in an airtight container at room temperature for up to four days after preparing.
