Here are the missing instructions: Heat tortillas directly over a medium flame of a gas stovetop, or in a cast-iron pan over medium-high heat until pliable, about 10 seconds per side. Place 2 heaping tablespoons of filling on one end of each tortilla, and spread slightly. Starting at filling end, gently roll tortilla into a tight cigar shape. Secure seam side of taquito my piercing opposite side with a wooden pick just until pick pokes through. Place rolled taquitos, seam side down, on a plate; cover with plastic wrap, and place a clean kitchen towel over plastic wrap. Heat 3/4 inch oil in a high-sided skillet over medium-high heat to 350 degrees F. Working in batches, gently lower rolled taquitos, seam side down, into hot oil, and cook, undisturbed, until seam side is golden and crisp, about 2 minutes. Using two forks, flip taquitos. Remove picks, and cook until crisp and golden all over, about 2 minutes. Using tongs, remove cooked taquitos from oil, and drain on a wire rack set inside a rimmed baking sheet. (Between batches, skin surface of oil with a fine wire-mesh strainer to remove any particles as needed.)
My problem was that the filling came out while frying. Just left with half-empty taquitos and a skillet of oily potato-poblano mixture. (I got the instructions in the print version.)
It says to follow the assembly instructions "at left" and there's nothing there.
