Heat oil in a 3-quart saucepan on medium high heat. Put 3 or 4 popcorn kernels into the oil and cover the pan. When the kernels pop, add remaining kernels in an even layer with seasoning mix. Cover, remove from heat for 30 seconds. Return the pan to the heat. Once popping is steady, gently move pan back and forth over the burner. Keep lid slightly ajar to let the steam from the popcorn release. Once popping slows to several seconds between pops, remove pan from heat, remove lid, and dump popcorn into a wide serving bowl. Serve and enjoy!
