Holishkes (also holipches or huluptzes or prokes or gefilte kroit) is a traditional jewish cabbage roll dish. holishkes are prepared from blanched cabbage leaves wrapped in a parcel-like manner around minced meat and then simmered in tomato sauce. sometimes rice is added to the meat filling. while the dish is eaten all year round, it is customarily served on sukkot to symbolize a bountiful harvest, and on simchat torah because two stuffed cabbage rolls placed side by side resemble torah scrolls.
