Romaine - Jay has to be the number one choice. Tom Kerridge. Andi Oliver
I'd have Jay too although I suspect he's happier writing about food than he is presenting a TV show.
Andi Oliver would be good. Tom Kerridge would be excellent. James Martin?
Finding the 'Chef' host would probably be easy; finding them 'Not-a-chef-but-knows-a-bit-about-food-and-is-natural-presenter' is more tricky imo.
