This video was recorded during a 6 month period, obviously I did have a lot of problems with the chocolate extruder. However, I do want to say that if you think this is a really interesting subject and would like to buy an extruder kit, keep in mind that most chocolates probably will not work. The chocolate I found that worked the best was with the two main ingredients being sugar and vegetable fat. The chocolate I tested was lacking cacao which I think was the main reason it worked much better than the previous tested chocolates.
