Caramel Popcorn

I love caramel popcorn. I am still in search of the perfect soft caramel corn recipe, so this will have to do until I find it. I prefer the soft caramel corn, but this is an awesome crispy recipe. It never seems to last too long at my place.



1 cup butter
2 cups brown sugar
1/2 cup corn syrup
1/2 teaspoon salt
1/2 teaspoon baking soda
5 quarts popped popcorn (I used 2 bags microwave popcorn)
