2 c. packed brown sugar
1/2 c. Karo syrup

Pop popcorn and place in a large brown grocery sack -- set aside.

Mix all ingredients, EXCEPT soda, in a large mixing bowl. Cook on high for approximately 5 minutes or until all the ingredients are melted. Cook on high again until mixture reaches a full boil. Continue cooking at a full boil for 2 additional minutes. Take out of microwave and add the baking soda, mix thoroughly.

Pour 1/2 of the hot syrup into brown bag of popcorn, close and shake well. Add the remaining 1/2 of syrup and shake again. Place the bag back into the microwave and cook on high for 1 1/2 minutes, remove and shake. Again, cook on high for 1 1/2 minutes, remove and shake.

Spread out on cookie sheets or aluminum foil to cool (no need to butter/grease cookie sheets). Rent a good movie and enjoy!!!
