Heat 2 tablespoons vegetable oil in a large pot over medium heat
Add 3 popcorn kernels and cover the pot
When the test kernels pop, add 1/2 cup popcorn kernels and 1/4 cup sugar
Cover the pot and shake it gently every few seconds
Keep the lid slightly ajar to let steam escape
Remove the pot from heat when popping slows to 2 to 3 seconds between pops
Immediately pour the popcorn into a large bowl
Sprinkle with 1/2 teaspoon salt
Toss well to coat evenly
Let cool before serving
