1 c. sugar
1/3 c. light corn syrup
1/4 c. butter
1/2 c. water
1/2 tsp. salt
1 tsp. vanilla
2 qts. pop corn

Keep pop corn warm in 250 degree oven. Cook the first 5 ingredients over medium heat, stirring constantly until mixture comes to a boil. Continue cooking without stirring until mixture reaches 270 degrees on a candy thermometer or until a small amount separates into hard threads when dropped into very cold water. Add vanilla and stir. Pour syrup over popped corn, mixing with a fork.. When cool enough to handle but still quite warm, form into balls.
