Warm tortillas. Warm the tortillas in a dry skillet, one at a time, for about 30 seconds per side over medium heat. Keep wrapped in a clean kitchen towel until you are ready to assemble.
Fill flautas. Working with one tortilla at a time, place about 2-3 tablespoons of pork along the edge of the tortilla closest to you. Roll the tortilla around the filling and secure with a toothpick. Repeat with the remaining tortillas and filling.
Fry flautas. Pour the oil into a high-sided frying pan and heat over medium heat until the side of 1 flauta fries in 30 seconds. Add the flautas 3-4 at a time, making sure not to crowd the pan, and fry until crisp and golden brown, about 1-2 minutes per side. Transfer to a paper towel-lined plate and repeat with the remaining flautas. Remove the toothpicks before serving.
Serve. Serve warm with whichever garnishes you desire. My personal favorite is to combine tomatillo salsa and sour cream together and serve that as a dipping sauce.
