Created in response to a recipe request. The basic recipe I started with tasted like a bitter Hershey's chocolate syrup. I didn't like that, so I tried again. I sweetened it up, gave it a flavor kick, and the second batch was perfect. It has the consistency of homemade caramel, which makes this hot fudge sauce live up to its name. As written this recipe makes 2 cups (a pint canning jar) of sauce, but when doubled it fills a quart-sized jar. This would be a fun recipe to double and fill jelly jars for gifts.
