Prepare Topping: In a small bowl, combine the powdered sugar and cayenne pepper. Set aside.
Assemble Taquitos: Cut the panela cheese into strips, approximately the size of string cheese. Place one cheese strip inside each corn tortilla and roll it up tightly. Lay the rolled taquitos seam-side down on a tray. Gently press the seam with a wooden spoon to help it seal.
Fry Taquitos: Heat a cast iron skillet over medium-high heat with a light coating of oil—the oil should just cover the bottom of the pan (do not deep fry).
Seal and Crisp: Carefully place the rolled tortillas into the hot pan, seam-side down. Hold the taquitos gently with the wooden spoon until the bottom side is browned and the tortilla seam is sealed shut.
Finish Cooking: Rotate the taquitos to brown and crisp the remaining sides, leaving one side untouched, until they are golden and crisp all over.
Season and Serve: Remove the taquitos from the pan and immediately sprinkle lightly with salt while they are still hot. Drizzle
