My gran always used to serve yorkshire pudding with any meat, but not with poultry, and never with Christmas dinner. I only ever serve it with roast beef, as did my mum. This year, my daughter and her boyfriend are hosting Christmas day for us all, and his family have asked if she can do yorkshires ... it was a very firm 'no!' She told them that yorkshires don't belong on a turkey dinner, and if they wanted them they'd have to make their own and bring them on the day, as there won't be space in her ovens (she has two full-sized ovens, but won't be making space for yorkies!Lol).
