Sister Mabel'S Caramel Corn - cooking recipe

Ingredients

2 c. light brown sugar, firmly packed
1/2 c. light corn syrup
1/2 lb. butter
1/4 tsp. cream of tartar
1 tsp. salt
1 tsp. baking soda
6 to 8 qt. popped corn

Preparation

In a 2-quart saucepan, combine brown sugar, corn syrup, butter, cream of tartar and salt.
Bring to a boil over medium heat, stirring constantly.
Boil rapidly for about 5 minutes, until mixture reaches 260\u00b0 on candy thermometer.
This is the hard ball stage.
You can also test this by dropping a few drops of syrup into ice water.
The syrup should form a firm ball that holds its shape, but is still pliable.
Remove from heat.
Add baking soda quickly, but thoroughly.
