British Foods

[Barbara]

I didn't know if this was worth posting on the main list so I'm 
posting it here. 

I'm from the US and I'm reading the scene in GoF where they're 
having their first feast. Never having been to the UK, I have no 
idea what some of the foods are that they're eating. Can someone 
enlighten me as to what these foods are (and what they're made from) 
so I can get a better sense of Ron's gustatory enjoyment?

treacle tart, spotted dick, chocolate gateau, Yorkshire pudding

And if there's anything else written in the books that might be a 
British delicacy or specialty, please feel free to mention that too!
