It is the old fashion kind that you have to stir at the end to loose the gloss.
First I burned the first batch, so I had to start over.
Second, it did not want to cook to the soft ball stage, maybe my candy thermometer is broken. So I took a chance after cooking for while, and let it cool for the final mixing stage.
Then I mixed for a really long time, remained glossy, so I gave up on it for while.
Then I thought I would reheat it, a layer of fudge just got hard on the bottom of the pan.
I finally gave up, salvaged what I could, put it in the fridge, and went to bed.
In the morning, I was surprised to find that my fudge actually looked and tasted like fudge.
It's a miracle!
