Carmel popcorn.

1/2 cup butter
1 cup brown sugar
1/4 cup karo syrup
1/2 tsp salt

Microwave all the above for 1 min and 30 seconds, stir. Then add:

1/2 baking soda
1/2 tsp vanilla
3/4 cup popcorn (already popped)

Mix all of that together and bake at 300 degrees for 20 minutes. Stir every 5 minutes. My friend Monica gave me this recipe.
