1 c. milk
1 tbsp. light corn syrup
1/2 c. butter, divided

Combine the first 4 ingredients in a large pan. Cook over medium heat, stirring constantly until sugar dissolves. Add 2 tablespoons butter. Stir until butter melts. Cover and boil mixture 3 minutes. Remove cover and continue to cook, without stirring until mixture reaches a soft ball stage, 234 degrees.
