To make homemade kettle corn, heat vegetable oil in a large pot, add popcorn kernels and sugar, stir, and cover with a lid. Shake the pot every few seconds once the kernels start to pop, remove from the heat, sprinkle with salt, and serve immediately. Another option is to use powdered sugar when the kernels begin to pop and then use granulated sugar to coat the popcorn when the popping slows.
To make 4 cups of homemade kettle corn, heat 1/4 cup of vegetable oil over medium-high heat in a large pot until hot but not smoking. Add 1/2 cup of popcorn kernels and 1/3 cup of granulated sugar, stir, and then cover with a lid. Shake the pot every few seconds for three to four minutes until the popping slows, then remove from the heat, and pour into a large bowl to prevent caramelizing or burning. Sprinkle with 3/4 teaspoon of salt, and serve.
Another option for homemade kettle corn is to use 1/2 cup of powdered sugar in place of the granulated sugar when you add the kernels to the oil. When the popping slows, sprinkle with 2 tablespoons of granulated sugar, shake until the popping has stopped, sprinkle with coarse salt, and serve.
