Heat enough coconut oil to cover the bottom of the pan on medium-high heat. Add a couple of kernels of popcorn.
When they start to pop, add the add the remaining kernels.
Keep the pot moving, vigorously shaking back on forth over the burner, still on medium high, to prevent burning. Don't leave it sitting on the heat source.
As soon as you hear popping kernels, add the maple syrup and continue to shake the pot.
When the kernels are popped, use a wooden spoon to remove the unpopped kernels. Pour the popcorn out into a bowl, add salt, and give it a good shake.
