Caramel popcorn

12 c popcorn, air-popped
1 c brown sugar -- packed
1/2 c corn syrup
1/2 c margarine -- melted
1/2 tsp salt
1/2 tsp baking soda
1/2 tsp vanilla

Preheat oven to 300. Place popped corn in oven while preparing caramel
glaze. In medium saucepan, combine brown sugar, corn syrup, margarine, and
salt, about 7 to 10 minutes. Stirring constantly, bring to a boil over
medium heat. Without stirring, boil 4 minutes. Remove from heat; stir in
baking soda and vanilla. Pour over warm popcorn; toss to coat well. Bake
60 minutes, stirring every 15 minutes. Turn popcorn mixture onto a large
piece of foil. Cool completely. Break mixture into small pieces. Place in
large bowl.
