Preheat oven to 225F.

Place popped popcorn on two large baking sheets or roasting pans and divided nuts among the two pans.

Salt the popcorn.

In a large saucepan bring butter, brown sugar, and corn syrup to a boil, stirring constantly.

Let boil for 5 min. on medium heat without stirring.

Remove the saucepan from heat and stir in vanilla and baking soda.

Pour over the popcorn and stir to coat.

Place the pans in the oven. If they both don't fit you will have to bake one and then the other or you can halve the recipe.

Stir every 10 min. so that the mixture does not burn. Bake for 1 hour. Let cool completely and then store in Ziploc bags or sealed containers. Yum!!
