Yep, that’s exactly what she does. I’m not sure where she finds it now when she does get it. It seems like they had it at one of the base commissaries at one time. I know she got a MEGA jar of it for my Marmite loving brother at an English store one time. It was huge. I think it cost about $20.
I can get a tiny jar at a local speciality store ...
But its not cheap..
