I love how quick this recipe is to put together. It probably isn't the most Christmas-y of recipes, but that is when it's become a tradition to make it in my family. This would probably be great at Haloween as well.
1/2 cup butter or margarine
1 cup packed brown sugar
1/4 cup light corn syrup
1/2 tsp. baking soda
1 cup peanuts
8 cups popped popcorn (1/3 cup unpopped)
In three quart glass bowl, combine butter, sugar and syrup. Cook in microwave on High for 3 minutes.
Stir. Add baking soda and stir gently until light and foamy. Cook 1 ½ minutes.
Stir in nuts. Add popcorn (make sure you remove any un-popped kernels first) and stir until well coated. Cook 1 ½ minutes.
Spread mixture onto buttered parchment paper. Let stand at room temperature for 1 hour to harden. Loosen mixture form parchment paper and break into pieces.
