2 bags of microwave popcorn
Pop the popcorn and place in large brown paper bag.
Combine margarine, brown sugar, and syrup in a 4 1/2 C.Tupperware Heat 'N Serve. Heat on high for 5 minutes, stirring once every 2 1/2 minutes. Stir in baking soda. Mixture will foam!
Pour over popcorn in bag and shake. Place bag in microwave and heat on high for 1 minute. Shake, heat 1 more minute, shake.
Store in airtight container.
(Note: There's no reason this recipe wouldn't work with standard popped popcorn. Place popped corn in an 8-Cup Heat 'N Serve. Pour syrup over corn, seal, and immediately shake well. Heat in microwave on high as above, etc.)
(Note from Terri: "Just thought you would like to know: I have used this recipe for years!! You can use regular popcorn, in fact I think it tastes better than the microwave popcorn. And a little hint...lightly spray the inside of the paper bag with Pam Cooking Spray-no mess at all."
