I always make gravy using drippings, stock and Gravy Master. I am stuck at mom's, cannot go to the store. I have no Gravy Master, no giblets and no bouillon so can't make stock. Long story but I ended up with a raw pre-prepared turkey from Omaha steaks. The thing came with no giblets. I have pre-made dishes of the fixings, but they did not include enough gravy. I need to make more. The turkey has been roasted (we are eating early tomorrow, going to just reheat slices) and I have drippings, but I have no stock and no bouillon to make stock. I have one onion and some celery and a few herbs (bay, oregano). I looked online for substitutes for Gravy Master but they say use beef base which is bouillon I guess but I don't have any. I might be able to separate the fat from liquid in the drippings and get some non-fat liquid but I don't think it will be enough. Should I try to make a vegetable stock out of the onion and celery? And what should I do for Gravy Master? Any other ideas? Edit: I have flour of course, to make the roux. Do I just brown it more than usual?
