Heat coconut oil or butter in pan with a kernel or two. When the kernel pops, add in the rest of the popcorn.
When it really gets going, make sure to shake the pan around a bit and release a bit of the steam. This helps it to remain crunchy and also keeps it from burning. And then just like with the microwave stuff, once you can count a few seconds between pops, take off the heat source so as not to burn.
Pour into a large bowl and then melt a couple more tablespoons of butter in the hot pan. Pour over popped corn, stir, and add salt/seasonings to taste.
