Grandma's Caramel Popcorn Balls

1 . Stage

Sort through popcorn, discarding unpopped kernels.

Combine evaporated milk, sugar, corn syrup, margarine, and salt in a large saucepan over medium heat. Bring to a boil; stir constantly until caramel reaches 246 degrees F (119 degrees C) on a candy thermometer, about 5 minutes.

3 . Stage

Pour some popcorn into a very large bowl. Pour in some of the caramel; stir until evenly coated. Add remaining popcorn and caramel in batches, stirring well after each addition.

Scoop some of the popcorn mixture onto a piece of plastic wrap. Gather and twist the plastic wrap to gently shape into a ball. Place popcorn ball on a baking sheet lined with parchment paper; repeat with remaining mixture. Let cool until set, about 15 minutes.
