Heat the oil in a wide pan with a lid over medium heat. Place 3 kernals of corn in the oil while it heats. Oil is ready when all three kernals have popped. Then put the rest of the kernals in and sprinkle sugar over the top. When the kernals start to pop, every few seconds, lift the pan to about 6 inches above the burner and shake for 10 to 15 seconds. Alternate between the stove and shaking until the pops are less frequent or have stopped altogether. Be careful not to burn the popcorn!
If you are worried about it burning, carefully pour out some of the popped kernals into a bowl and then finish popping the rest. Be careful with this, though! Flying hot popcorn kernals hurt! Put all of the popcorn in a large bowl and sprinkle with salt and serve! This is so, so good!
