In a heavy-bottom pot, heat the coconut oil on med-high heat until 3 test kernels pop.
Discard those kernels.
Stir in the popcorn until coated in oil.
Place the lid on the pot.
Shake the pot (not on the element) with the lid held firmly in place every 15 seconds so nothing sticks.
Keep cooking until the popcorn is popping once every 3 seconds or so.
Immediately pour into a bowl, drizzle with the "optional" melted butter.
Shake it up to distribute the butter, and repeat with 1/8 - 1/4 tsp of your favourite seasoning (salt works).
Makes around 5 cups
