Ingredients
2 cups brown sugar
1 cup margarine
½ cup light corn syrup
1 tsp salt
1 tsp baking soda
1 tsp vanilla
6 quarts popped popcorn (Nancy says to use stove popped - not air-popped or microwaved, but I use three bags of light butter flavored microwave popcorn, and it works fine)
Preparation
Combine sugar, margarine, corn syrup, and salt. Bring to boil. Boil 5 min then add baking soda and vanilla. Stir. Pour over popcorn. Put in large pan and bake at 200 for 45 minutes, stirring every 15 minutes.
