Measure spices, salt and olive oil into a cup. Add garlic powder into spices and oil mixture and mix well. Put a small rubber spatula in the cup, ready to help pour out the mixture. Have the spice mixture ready by the popper. Have a large bowl ready to pour the popcorn into.
Put olive oil and popping corn in the popper. Fasten the lid securely. Begin stirring, using high heat. Popping will start in about 2 minutes. Continue stirring until popping almost stops.
Remove from the heat, open the lid and sprinkle in the spice mixture. Then close the lid and continue stirring with no heat for several more rounds until the spices are mixed thoroughly. Pour into bowl and serve.
