Gribenes
Gribenes or grieven (, , "scraps") ) are crisp chicken or goose skin cracklings with fried onions, a kosher food somewhat similar to pork rinds. Gribenes are a byproduct of schmaltz preparation.
A favored food in the past among Ashkenazi Jews, gribenes is frequently mentioned in Jewish stories and parables.
