I made these tonight and they are delicious!! I've never made any type of candy before and these turned out better than I had hoped for. I did not have a candy thermometer(probably why I don't make candy) so I used the softball method which worked really well. It took 12 minutes for the mixture to boil to the right consistency to pass the softball test, after which I removed it from the stove, let it sit for about 2-3 minutes then added the vanilla and chopped pecans. It did thicken up very quickly at that point and since I was a little slow forming the balls(which weren't really round but I guess that comes with practice) it became too hard to work with. Twice I had to put the remaining mixture in the microwave for about 30 seconds which softened it up again. Other than that this was a great recipe for a first time try at candy making. Will definitely make again. Thanks for posting.
