I remember you went to Prague. Yes, the Jewish section of Prague is a very unique section. Prague has the oldest synagogue and Jewish cemetery in Europe.It's lucky that they were not destroyed during WWII.

There are many types of dumplings made in CZ. Dumplings are called "knedliky" in Czech. There are even different preparations for potato dumplings. If you would like a recipe for the most common type of Czech potato dumplings, just let me know. I have made them a number of times. I believe they do require a special Czech flour to make, but there is a way to make up for that with a product available in most US grocery stores.
