Chicken Broiled Liver (often sold labeled as Kashered or Flame-Broiled Chicken Liver) is a fully cooked, deeply rich, and nutrient-dense organ meat. In traditional Jewish and kosher cooking, chicken liver must be flame-broiled by law to remove internal blood before it is considered kosher and safe to eat. Because of this intensive initial process, grocery stores and specialized kosher butchers sell it pre-broiled and ready-to-eat right out of the package.
