Having chicken and beef brisket - which meat would you make the gravy from?

[Fufumcgoo]

I'm leaning towards beef, but I'm putting red wine in the beef and white wine in with the chicken.

Or would you just make two gravies and let people choose?

Yes make two!

Making two is a good plan for choice, if you can only do one do it from the beef - beef is unquestionably the king of roasts.

I’d make both, but I’m a bit of a gravy freak.

If it was me I’d make both.
