American Jews, who for the most part were of Eastern European ancestry, incorporated into their cuisine many foods and dishes that were traditionally cooked and treasured by their ancestors. I Modern times American Jews also incorporate into their cuisine traditional Jewish foods from other parts of the world.  

As many Jews keep a Kosher Kitchen (these are ritually correct dietary practices -  for example, meat products may not be eaten together with milk products but have each to be eaten separately with strictly designated time spans between them)  you will find that many of the recipes follow these dietary practices.

Below are a few links to Jewish website that will provide you with recipes ( and some times also video tutorials) on how to prepare Jewish food:
