In a large stock pot, heat the ¼ cup coconut oil over medium-high heat until completely melted.
Add in ¼ cup granulated sugar and ½ cup unpopped popcorn kernels, shaking or stirring until all the kernels are coated.
Cover the pot and continue to cook until the first kernel pops.
Once the kernels start popping, continuously shake the pot while listening for a break in popping. When you count 2 seconds between popcorn pops, remove the pot from the heat and take off the lid.
Pour the popcorn onto a large baking sheet or into a large bowl, sprinkle with ¼-½ teaspoon fine sea salt, and toss to coat.
Let cool for a few minutes to allow the sugar to harden, then enjoy.
Notes
Important safety note: because of the stickiness of the sugar, unpopped kernels tend to stick to popped pieces instead of falling to the bottom. To protect your chompers, you can pick out unpopped kernels or just keep an eye out for them while you enjoy.
