Gefilte fish (/ɡəˈfɪltə fɪʃ/; from Yiddish: געפֿילטע פֿיש‎, "stuffed fish") is a dish made from a poached mixture of ground deboned fish, such as carp, whitefish, or pike. It is traditionally served as an appetizer by Ashkenazi Jewish households. Historically it consisted of a minced-fish forcemeat stuffed inside the intact fish skin. By the 16th century, cooks had started omitting the labor-intensive stuffing step, and the seasoned fish is most commonly formed into patties similar to quenelles or fish balls. These are popular on Shabbat and Jewish holidays such as Passover, although they may be consumed throughout the year.
