Microwave Caramel Popcorn

3 to 4 quarts popped corn
1  cup brown sugar
1 stick margarine
1/4 cup white corn syrup
1/2 tsp salt
1/2 tsp baking soda

Combine brown sugar, margarine, corn syrup, and salt.  Bring to a boil in microwave.  Cook for two minutes on high, stirring in baking soda, well.  Pour over popped corn in a brown paper bag.  Fold bag shut and microwave 1 1/2 minutes on high without shaking.  Then shake well.  Microwave another 1 1/2 minutes.  Serve warm.  Enjoy!

I like to "dry this out" by leaving it opened on the counter overnight, as well.  It gives it a more candy-like texture.  Warning: Do not try to eat this if you need dental work, because once you start eating it, you may not want to stop!
