P'tcha, fisnoga or galareta (also known as "calves' foot jelly") is a traditional Ashkenazi Jewish dish.
[2] In Eastern Europe, Jews served p'tcha with chopped eggs on Sabbath.
The Encyclopedia of Jewish Food describes it as a delicacy made from one of the least expensive parts of the animal.
[3] The Second Avenue Deli in Manhattan was one of the few Jewish restaurants in the United States that still served p'tcha, but does no longer.
Given the small and dwindling customer base, p'tcha is made to order upon request.
