Add the canola oil and 3 popcorn kernels into a 6 quart saucepan.
Cover and cook over medium-high heat until all 3 kernels have popped.
Add the remaining kernels, cover, and remove from heat for 30 seconds. Then return the pot to heat and the kernels should begin popping within a minute
Cook, shaking occasionally until the popping sound slows, approximately 2 minutes.
Near the end of popping, lift the lid slightly to let out steam and keep popcorn crisp.
Melt butter in a pan toward the end of popping.
Pour popcorn into brown paper bag, and pour over melted butter.
Shake the bag to coat evenly, then add in powders and shake again.
