Ingredients for Christmas Carmel Corn

Have these ingredients available:

2 Cups Packed Brown Sugar (light brown or dark, your choice. We enjoy the light brown.)
1/2 cup Dark Karo (has good taste.) Light is ok if not artificial flavored. (Can use 1/4 c. of ea).
2 sticks (1 cup) Butter. (not artificial).
1/4 tsp salt
1/4 tsp cream of tartar
1/2 tsp soda (add later).

Melt butter in 4 to 6 qt pan. Add Karo, brown sugar, salt and cream of tartar--then bring to boil. Boil about 5 minutes, until bubbles begin to thicken.
Remove pan from heat. Add 1/2 tsp soda, and stir in. Syrup will foam up.
Pour over popped corn (5 or 6 gallon?? and mix in, using wooden spoons)
Then heap coated corn up on cookie sheets, and bake @ 200 degrees for 1 hour. See Popped Corn Label.
