Preparation

• Preheat oven to 250 degrees F. Place popcorn in a large, shallow non-stick roasting pan.
• In a heavy saucepan, mix sugar, butter, and corn syrup.
• Stir over medium heat until boiling; continue boiling for 5 minutes without stirring.
• Remove from heat, then add vanilla and baking soda.
• Immediately pour over popcorn and stir to coat.
• Bake in preheated oven for 1 hour, stirring several times (the stirring is key because the caramel will keep settling on the bottom and you need to scoop it up and stir it back into the popcorn).
• Cool, break apart and store in a tightly sealed container.
