Notes: For a vegan version, use coconut oil.
Do not raise the heat about medium-low, and if the sugar looks almost completely melted before the second round of kernels begin to pop, reduce the heat to low.
Shaking the pan back and forth every 2-3 seconds will also help prevent the sugar and popcorn from burning. It's better to shake the pan too much than too litte!
