Kishke is a Jewish (specifically Ashkenazi) traditional sausage of a fowl intestine stuffed with matzo meal, suet and spices. The cooked kishke is a grey-white color.
Kishke is available in some kosher butcher shops and delicatessens.
Kishke is also used in its original East Slavic meaning, intestine or gut, as an English-language Yiddishism: for example, my kishkes are aching since I ate those blintzes.
