I have never tried it purelife, but it sure sounds interesting. I watched a program the other day where a guy was making them. They look super simple.
If you want to try them, you really don't need a deep fryer.....as a matter of fact, I would recommend NOT using a deep fryer.
The quality of home deep fryers is not very good. We had one, and ditched it for a much more expensive model....it is no better......you'd need something of commercial quality for it to maintain the heat when you place the food in it. The temp drops too quickly in the home appliance variety. You can get better results with a deep pot on the stove.
