The technique of making chimney cake or kurtos kalacs is not as difficult as it seams, as you will see in this post.
The recipe and indications are in the first part of this kurtos kalacs series, there is a link at the end of this post.
When you've read them already, just watch this video for making the job easier.
I've recorded a live demonstration of how kurtos kalacs is made, at the outdoor cooking championship. These young people from team 10 at the competition, really make it look easy.
Have a look at the video and give it a try!
