Ingredients
- 16 cups popped popcorn, unsalted
 - 2 cups Karo® dark corn syrup
 - 2 cups brown sugar
 - 1 cup water
 - 1 tablespoon vinegar
 - 4 tablespoons whipped butter
 
Preparation
- Pop popcorn and put in a large bowl. Set aside for use later.
 - Mix syrup, brown sugar, water and vinegar in a saucepan. Cook over medium heat, stirring constantly until mixture boils. Continue cooking and stirring almost constantly about 15-20 minutes on medium heat. Cook to hard ball stage (until a small amount of mixture forms a hard ball when tested in very cold water.)
 - Remove from heat, quickly add butter, and stir.
 - Slowly pour mixture over popped popcorn in a large bowl, while mixing well. Form into balls, using as little pressure as possible.
 - Wrap each popcorn ball in plastic wrap and store in an airtight container.
 
Helpful hints
- Butter hands, or better yet, wear rubber gloves with butter on them. The popcorn won’t stick as bad and is not as hot!
