01 - Combine mashed sweet potato, cassava flour, olive oil, and salt in a large mixing bowl. Mix by hand or spatula until a slightly sticky dough forms.
02 - Add warm water one tablespoon at a time if the dough feels too dry or crumbly. Continue mixing until the dough holds together well and becomes pliable.
03 - Divide the dough into 8 equal pieces. Roll each piece between your palms to form smooth, round balls.
04 - Place one dough ball between two sheets of parchment paper. Press flat with your hands, then use a rolling pin to roll into a thin circle approximately ⅛-inch thick. Repeat with remaining dough balls.
05 - Preheat a nonstick skillet or cast iron pan over medium-high heat until hot but not smoking.
06 - Cook each tortilla for 1-2 minutes on the first side until lightly browned with small dark spots. Flip and cook the second side for 1-2 minutes until cooked through. Transfer cooked tortillas to a plate and cover with a clean cloth to maintain warmth and flexibility.
07 - Serve immediately while warm for best texture and pliability. Use for tacos, wraps, or as a side dish.
