Place the neutral oil and popcorn kernels in a large pot with a lid, then place over medium heat. When you start to hear popping noises, use oven mitts to shake the covered pot until you hear the popping noises subside.
Remove the popcorn from the heat, then mix in the extra virgin olive oil, cheese and jalapeno. Toss to coat, making sure to scoop up any settled jalapeno bits from the bottom.
Serve immediately.
Recipe Notes
You could pop the popcorn in an air popper or even use microwave popcorn in a pinch.
Replace the parmesan cheese with another kind of cheese or nutritional yeast to make this vegetarian or vegan.
This popcorn does not store well due to the moisture from the jalapeno, so eat immediately. You can try to toast it in the oven or toaster oven to regain its crispiness, but this is only effective on day 1.
