1. Heat vegetable oil in a large pot over medium heat. Stir in popcorn kernels and sugar.
2. Cover and shake the pot constantly to prevent sugar from burning. When popping has slowed to once every 2 to 3 seconds, remove the pot from the heat and shake for a few minutes until popping stops.
3. Pour popcorn into a large bowl and allow to cool, stirring occasionally to break up large clumps.
