It's, Jewish Haggis.
Oy vey, don't get me started on kishka. I love the stuff!
My late mother used to make a version that I loved. She would buy a large Kosher chicken to pot roast but, she took the skin of the neck and stuffed it with a mixture of flour, gribenes, (bits of chicken skin, onions and garlic fried in chicken fat). After sewing the neck skin to form a "tube", she stuffed in the mixture and threw it in the pot to cook with the chicken. Ahh, talk about eating a bit of heaven! Of course, eat it too often and you'll be eating it, IN heaven.
