2 c. white sugar
1/2 c. white syrup
2 tbsp. vinegar
4 tbsp. water
6 tbsp. butter
4 drops yellow cake coloring

Boil until brittle. Use a candy thermometer or when placed in cold water candy will be brittle hard. Pour into a buttered cake pan. Keep cutting in squares as candy hardens with a buttered knife. (Watch candy and stir often as it will burn easily.)
