What is a "platar"?
I've seen them recently in the Williams Sonoma catalogues and in their stores, though I don't think they were cast iron. They looked more like a heavy aluminum with a non-stick coating.
There are similar pans with round indents that do not form balls but flat "cakes".....
A Plat Pan is used to make Platar. A little version of a "Swedish Pancake". It is cast iron, with seven round very shallow wells that are flat not rounded on the bottom. The other pan peaple are talking about is not a swedish food, but from Norway. They are hard to find in America these days. When you do they are antque and not cheap or made in china and low quality.
