The "wonder pot" is a type of stovetop bakeware that seems to have been popular in Israel during a period of austerity. I'm looking for a (preferably USA based) supplier for a new one.
My mother had a similarly shaped pan with a lid that she'd use for baking coffee cake and such when camping. It was all aluminum and much less complicated (and likely not as useful) as what your talking about. The closest thing I found is the Omnia Oven.
It looks they may be had for about $50.
My company now distributes the Omnia Oven which is a modern version of a wonder pot. These are available at http://lunatecgear.com/products/travel-gear/omnia/ and Amazon.
You are welcome to contact us if you have questions about Omnia. 858.653.0401
I tried my darndest to find a good answer for you, but I'm honestly not convinced that these are still being made! Here is a link to an antique one on Ebay.
