Nic, I can't answer your question re special gravy from pan juices (wish I could! Pan juice gravy is delicious I think), but what I was going to say is that if the alcohol in whatever you use is cooked off, then I thought it would be okay. I was wondering the same thing (but for my toddler to eat and me been pg atm), and hope someone might be able to confirm that?

I've noticed that the gravy powder boxes have directions for pan juice gravy on them.
