1/2 cup popcorn
1/4 cup vegetable oil
1/2 cup sugar
1 tsp salt
1. Once the vegetable oil is hot, add the popcorn and sugar. Swirl to coat popcorn kernels. Cover the pot and shake it every couple of seconds once the popcorn starts popping.
2. As soon as the popping slows down (about 3 minutes), remove the pan from the heat and empty the popcorn into a large bowl. Sprinkle with salt and toss.
Very important tip: remove the popcorn from the heat as soon as the popping slows down. Don't wait until every last kernel has popped. I did that the first time and ended up with a pot covered in burnt sugar.
If you somehow have any extra, it should keep in a closed container for a few days.
