Whenever I have ice cream, I feel as though I MUST have hot fudge to top it. And in my neurotic "I make everything from scratch" mode I decided to make my own!
I tried to make it once before but I didn't know that corn syrup was the culprit for making it that delicious chewy texture that hot fudge gets when it hits the ice cream. The first time I made it, it ended up more as a ganache and slightly gritty somehow. I'm not sure since I didn't add sugar to it.
I have to admit that the smell of bubbling gooey chocolate is one of the most intoxicating smells I've ever had going in my kitchen.
The recipe calls for unsweetened chocolate, which I had never had before. I also forgot to warn my husband that it doesn't taste good, so when he stuck his finger in the bowl I used to melt chocolate after it was done he made a very upset face.
Its so good that I generally had a little ice cream to go along with my bowl of hot fudge.
