To prepare this easy recipe, put a pressure cooker on medium flame and add potatoes in it with enough water. Close the lid and pressure cook them until soft or for 2-3 whistles. Once done, turn off the flame and let the steam release on its own. Then drain the water and take out the boiled potatoes in a bowl. Peel and mash them using a masher, as you don't want to burn your hands.
To make the filling, heat butter in a pan over medium flame and add crushed garlic to it. Saute for a few seconds and then add mashed potatoes to it. Sprinkle cumin powder and season with salt to taste. Mix well and remove from heat.
Preheat the oven at 180 degrees. Once done, microwave the corn tortillas for 30 seconds. Place the potato stuffing in the centre of each tortilla and add cheese over the stuffing. Roll the warm tortillas tight and place them on a baking tray. Repeat till all the tortillas are filled and rolled.
