2 c. light brown sugar
1/2 c. light karo corn syrup
1/2 lb. (2 cubes) butter or margarine
1/4 tsp. cream of tartar
1 tsp. salt (Grandma says she uses a little less)
1 tsp. baking soda
6 quarts of fresh unsalted popped popcorn
In a 2 1/2 quart saucepan, combine brown sugar, corn syrup, butter, cream of tartar, and salt (don't add the soda yet!). Heat to boiling; stir rapidly over medium-high heat. Do a hard boil: 260 degrees. Have soda ready; remove sugar mixture from heat and quickly and thoroughly stir in baking soda. Pour mixture over popcorn in a large roasting pan; stir gently. Bake at 200 degrees for one hour. Stir 2 to 3 times while baking. Remove popcorn from oven; turn out onto wax paper and pull it apart a little bit.
