I know this isn't the sort of candy everyone will like as it has a very strong, burnt flavour but if you do, I promise it will quickly become addictive and you should give half the batch away before you demolish it.
This is so dead simple to make, which is another reason you should plan to give some away-it can be made as a spur-of-the-moment sort of whim with ingredients you probably have on hand.
The recipe originally called for nuts, which I omitted. If you choose to add them, include 1/2 cup in the bottom of the pan, then pour the candy over it and proceed as the recipe indicates. The original was from From Amish and Mennonite Kitchens.
You Will Need:
1 1/2 cups granulated sugar
1 cup water
1/3 cup apple cider vinegar
3 tablespoons full flavour molasses
Line an 8x8 heatproof pan with parchment, then grease it lightly.
In a large, heavy pot (it will foam up so use a large pot) bring everything to a boil over medium heat. Cook until it reaches 300 degrees F. (hard crack stage). Remove from heat, pour in prepared pan, and when it begins to cool, score into neat squares. When fully cooled, break into squares and wrap tightly in wax paper. Immediately give half the batch away.
