Preheat oven to 250° then gather your ingredients, an air popper, and a large heavy bottom saucepan.

Pop popcorn with the air popper.

Melt butter, then add sugar, corn syrup, and salt. Boil 5 minutes, stirring constantly.

Take off the heat and stir in baking soda.

It will start to appear rise up and become fluffy.

Pour over popped popcorn and mix well until the popcorn is all coated. If you don't have a huge bowl you'll want to divide it into two bowls to do this.

Spread on to 2 greased cookie sheets.

Bake for 30 minutes, stirring and rotating pans in the oven half way through.

Pull from oven and immediately scrape the candy popcorn from the sheet pans into a large bowl. Once into the bowl, break up the big pieces but not too small, about a child's palm size is perfect. Let cool.

Enjoy!
