1 lb. light brown sugar
1 tsp. vinegar
1/4 lb. pure butter
1 c. water

Use a deep kettle (size 8 inch wide, 4 1/2 inches deep). Put sugar in pan with cup of water. Place on burner and bring to a slow boil. Add butter and vinegar. Let simmer for 20 to 30 minutes until it reaches the brittle stage. Test same by dripping samples into cup of water. When ready, pour into a buttered pan, 7 x 11 inch. Let cool. Break into pieces and enjoy.

Note: Do not stir at anytime or it will get sugary.
