I want to start by saying that I make dozens of batches of fudge every fall, so I'm no newcomer to the fudge scene. This fudge has a wonderful flavor, but I found that I had to boil the mixture for longer than the 18 minutes the directions call for. My first batch didn't set up, so the second one I used a candy thermometer for and let it get to the softball stage (THE fudge stage) before pulling it off the heat. I think the 18 minutes probably worked for the specific stove the original author used, but probably the time will be different depending on the stove being used. I recommend using the candy thermometer and boiling it to the softball stage. Otherwise, wonderful recipe--very flavorful.
