Line a large baking sheet with parchment paper, and set it aside.
Heat the oil in a large pot over medium high heat.
Add three kernels of popcorn to the oil. Once the kernels pop, the oil is hot enough.
Add the remaining popcorn kernels, and shake the pan for about 10 seconds to help the kernels warm up.
Pour the sugar over the kernels stir them together.
Once the popcorn starts popping, shake the pan almost constantly to keep the bottom of the pan from burning as much as possible.
Let the popcorn pop until the popping just slows down, about 1 to 2 seconds between pops.
Transfer the popcorn to the prepared baking pan.
Sprinkle over the top with the salt.
Let the popcorn cool for a couple minutes.
Remove any burnt or unpopped kernels.
