Heat oil or butter in a pot or large pan over medium heat. Add a few corn kernels; when they start popping, add the rest and cover with a lid. Gently shake the pan occasionally to distribute the oil evenly and prevent burning.

As soon as the popping slows down, remove the pan from heat and transfer the popcorn to a large bowl. Season with herb spices and, optionally, salt. Mix well.

Sprinkle with grated cheddar cheese and enjoy!
