Add two tablespoons of coconut oil and 2–3 popcorn kernels to a large pot with a thick bottom.
Set the pot over medium heat and cover it with a lid.
Once the test kernels pop, remove the pot from the heat and add ½ a cup of popcorn kernels.
Gently shake the pot to evenly coat the kernels in oil.
Return the pot to the heat with the lid slightly ajar to allow steam to escape.
When the kernels start popping rapidly, carefully shake the pot every 10–15 seconds to prevent burning.
Once the popping slows to just a few pops per second, remove the pot from the heat.
Give it a final shake, then transfer the popcorn to a large bowl.
If you'd like to add flavorings (salt, melted butter, spices, or powdered sugar), now’s the time to toss them in while it’s still warm!
