I know. It’s not ‘natural’.
But if you’re planning to cook a frozen turkey you’ll be well advised to heed this word of advice learned by trial and error.
Before you pop that bird in the oven, reach inside from the opposite direction you’d figure and feel around a bit. There’s a better than even chance you’ll discover a plastic bag full of stuff they thought was too good to throw away, but not good enough to keep and sell, down at the turkey factory.
Leaving that bag of goodies inside when it goes into the oven will give you an interesting, scorched plastic flavor that’s definitely an acquired taste you mightn’t have cultivated yet unless you do a lot of your own cooking.
Once you have that bag of giblets in your hand there’s a lot you can do with them. Most of those options are the kinds of things your granny used to do, such as chopping them up and giving them a bath in grease or putting them in the dressing.
I don’t recommend trying it unless you are a veteran at such things. The crunched bread you were going to use for dressing makes pretty good croutons on salad. Non-discerning cats are a good target for the rest.
