Chewy Caramel

1 c butter
1 lb light brown sugar
1 (14 oz) can sweetened condensed milk
1 c light corn syrup
1 pinch salt
1 1/2 tsp vanilla

In heavy bottomed saucepa over medium heat, combine the butter, brown sugar, sweetened condensed milk, corn syrup, and salt.  Bring to a boil, stirring constnatly. Heat to between 234 and 240 degrees F, or until a small amount of syrup dropped into cold water forms a soft ball that flattens when removed from the water and placed on a flat surface.  Cook for 2 minutes at that temperature. 

Meanwhile, butter a 9x13 inch baking pan.  When the caramel is ready, pour into the buttered pan. Allow to cool completly at room temperature. Remove from the pan and cut into squares using scissors. Wrap individual pieces in waxed paper or cellophane.
