In a small bowl, mix together the nutritional yeast, smoked paprika, garlic powder, onion powder, turmeric and sea salt. Set aside.
In a large saucepan with a lid, heat the coconut oil on a medium-high heat for 1 minute.
Add three of the popping corn kernels to the pan, put the lid back on and shake it (using oven gloves - it gets hot!).
When you can hear that the kernels have popped, remove the lid and scoop them out with a spoon.
Add the rest of the corn kernels to the pan, replace the lid and shake vigorously.
Wait for them to pop, shaking the pan every 5-8 seconds to stop any popcorn burning.
When there is a break of about 6 seconds between the popping, remove the pan from the heat. (Accept that you won't have popped all the corn - it's just the way it goes!)
Sprinkle the seasoning over the popcorn while still in the pan, then place the pan lid back on and shake vigorously to combine popcorn and seasoning.
Pour into a large bowl and enjoy!
