There have never been any Amish communities in New Jersey, despite its proximity to many Amish communities in adjacent Pennsylvania and New York.
There are at least nine Amish food markets in New Jersey, however, including one near Princeton University called the "Pennsylvania Dutch Farmers Market," which has a 4.7 out of 5 star rating for its superb beef and other groceries at affordable prices.[1] Amish food markets are typically open three days a week, such as Thursday through Saturday (and never on Sunday, when the Amish strictly observe the Sabbath).[2]
