"So My Chocolate Should Have a Temper???" And Other Baking Discoveries

I'm getting ready to leave for Cambodia in two weeks and promised some friends I would make them some more red velvet cake truffles before I left.
But wait, these cake truffles, well...they look just like your cake balls?
Ah, you are quite right! Needless to say, I was bringing said cake truffles to my production team at church. And although it may seem silly, I felt that cake 'truffles' were much more PC than cake 'balls'. Am I right?

While my last recipe went over quite well, I didn't think the chocolate bark from Kroger was befitting of the title truffle, so I decided to use a higher quality chocolate. For this task, no 'chocolate flavored candy' would do.

Actually I just happened to have some bars of Ghirardelli semi-sweet chocolate on hand, so I figured it couldn't be that complicated. And I was right...at first. I used a double boiler and melted the chocolate bars (it took me a total of 8 bars). I pulled my red velvet cake balls out of the freezer, dipped each in the chocolate and then laid them gently onto a fresh sheet of parchment. Easy-peasy. The Ghirardelli chocolate made a marked improvement in the flavor and they looked pretty good too. I took them into church and to work the following Monday. They received rave reviews and a few people even expressed interest in buying some over the holidays and for a wedding.

The following morning however, I woke up and my beautiful cake balls, err, truffles looked like this (pictured below). I didn't refrigerate them and they were stored in a sealed container. What could I have done wrong?

These truffles had a bad temper!
As it turns out, chocolate should be tempered when used for coating or dipping. Yes, I had no idea what that meant until I Googled it. Those heinous looking spots are called fat blooms, and despite their appearance the chocolate is still fine to eat. Fat blooms are an accumulation of cocoa butter crystals on the chocolate's surface. One of the common causes is due to poor (or complete disregard of) tempering of the chocolate. If chocolate is properly tempered it will appear much more glossy and will form a crisp shell.

So there you have it. I guess some things are good with a little temper. Lesson learned for the Velveteen Baker. To avoid my little snafu, you can watch this video from Ghirardelli about how to properly temper chocolate.
