Combine popcorn and sugar in a small bowl and set aside.
In lidded, a heavy-bottomed pot that is still light enough to pick up and shake, heat oil over medium-high heat.
Heat until the first few whisps of smoke form and pour popcorn and sugar into the pot. Stir for about 30 seconds to distribute the sugar and place the lid on the pot.
Drape a towel over the top of the pot and onto the handles to keep your hands cool.
Every 30 seconds pick up the pot, hold on the lid, and shake all around. Return to the heat and repeat this process until most of the popping has stopped.
Remove the pot from the heat and sprinkle with salt to taste.
