Since I saved all the drippings off my 14 lb bird, probably over a cup along with all the brown bits and butter from basting. Wife had bought gravy mix but didn’t use it. Key is using the potato water in it. Got a lot of flavor from all the rosemary, thyme, and sage in the cavity along with the celery carrots, onions, and apple pieces. Put a lot of work into the turkey and probably the best one I’ve done. Great flavor and veryKudos to all of you smoking a turkey. That sounds like a lot of work. I'm exhausted from just roasting our breast in the oven and all the sides.
If I step out and give it a try next year, what do you do for gravy?
