Okay this is going to sound odd, but stay with me here... This video here http://www.jenniferdontz.com/viewproduct.php?itemid=dvd030 is actually a Cricut Cake designs video. HOWEVER among some of the little gems they added to the video is how to do a cake with chocolate curls the easy way!! In my opinion it's worth the price of the DVD. I don't own a cricut, nor do I have any plans to. But I LOVE this video for the extras they put in and would recommend it on that alone. Hope that helps!

Is it curls like Norman and Zane do? They sell a gadget to do it, but I think you can use a cirlcle cutter to make them. You can see them make them on one of the old challenge shows or you may be able to find a you tube video. I'll try to look tomorrow. Too tired now, sorry.
