Microwave Caramel Popcorn

Directions

1. 1
   Place popcorn in a large brown paper sack. (Like the kind you get from the grocery store.) Set aside.
2. 2
   In a large, microwave safe casserole dish, melt the butter. Stir in brown sugar, corn syrup, and salt. Cover and microwave on high for two minutes. Be careful the mixture will be very hot. Sir in baking soda. The mixture will foam up. Microwave on high for an additional 90 seconds.
3. 3
   Pour caramel over the popcorn in the paper sack and shake well.
4. 4
   Roll down the top of the paper sack and place it in the microwave. Microwave on high for 90 seconds. Shake again. Dump the popcorn from the bag onto a baking sheet to cool.
