Giblets are the edible internal organs of a bird, typically including the heart, liver, gizzard, and neck. They are often removed before cooking the bird, as they can have a strong flavor and can be tough if not cooked properly.
There are several reasons why you might want to remove the giblets from a bird before cooking it. First, as mentioned above, they can have a strong flavor that can overpower the taste of the meat. Second, they can be tough if not cooked properly, and can be unpleasant to eat. Third, giblets can contain harmful bacteria, so it is important to remove them before cooking the bird to prevent foodborne illness.
