Kashrut is the body of Jewish law dealing with what foods we can and cannot eat and how those foods must be prepared and eaten. "Kashrut" comes from the Hebrew root Kaf-Shin-Reish, meaning fit, proper or correct. It is the same root as the more commonly known word "kosher," which describes food that meets these standards. The word "kosher" can also be used, and often is used, to describe ritual objects that are made in accordance with Jewish law and are fit for ritual use.
here is no such thing as "kosher-style" food. Kosher is not a style of cooking. Chinese food can be kosher if it is prepared in accordance with Jewish law, and there are many fine kosher Chinese restaurants in Philadelphia and New York. Traditional Ashkenazic Jewish foods like knishes, bagels, blintzes, and matzah ball soup can all be non-kosher if not prepared in accordance with Jewish law. When a restaurant calls itself "kosher-style," it usually means that the restaurant serves these traditional Jewish foods, and it almost invariably means that the food is not actually kosher.
