1Start by cutting a paper grocery sack in half. This will serve as a makeshift serving bowl and it will absorb excess oil.
2In a 2 quart pot, combine the oil, margarine and popcorn. Set over high heat, and constantly shake the pan back and forth. After the first kernel of corn pops, place the lid on the pot, and continue shaking. When the popcorn starts to lift the lid up off the pan, remove it from the heat, and hold it over the paper bag until it stops popping.
3Pour into the paper sack and season with half of the seasoned salt. Shake the paper sack to distribute the salt. Taste before adding more so you don't make it too salty. You can always add more salt.
