My son and I made a tradition of making this every year when The Wizard of Oz came on television. Now days, you can watch The Wizard of Oz anytime you want to, but this would still make a nice memory.
6 quarts popped popcorn
2 sticks butter or margarine
2 cups firmly packed brown sugar
1/2 cup corn syrup
1 tsp salt
1/2 tsp baking soda
1 tsp vanilla
Melt butter in a large saucepan. Stir in brown sugar, corn syrup and salt. Bring to
a boil, stirring constantly. Remove from the heat and add remaining two
ingredients. (It will bubble up a bit, that is normal.) Pour over popped popcorn.
Mix well witha fork. Turn into two large shallow baking pans. Bake at 250
degrees F for one hour, stirring every 15 minutes. Set pans out of oven to cool.
For popcorn balls let cool slightly and gently press into balls. Or, once
completely cooled, break into pieces. Store in an airtight container at room
temperature for up to 3 days.
