SOOKIE: You know ham was originally made out of rice?
It definitely wasn’t – ham is, and always was, made out of pig. It is hard to know how ham even could be made from rice.
As a professional chef, Sookie must surely know this. I’d like to think that Sookie is making a “look how dumb I am” joke, in protest at Lorelai and Jackson putting her intelligence down. If not, perhaps she’s taken it to heart that Jackson prefers his women dumb, and is trying to give him what he wants.
