Brit-Speak: Food

[Lisa (Jennings) Mamula]

I, being the ignorant American that I am, have some more questions about 
Brit-speak, this time for food.  

1) What is all this talk about "puddings" and "tarts"???  I am especially curious 
about "treacle tart."  

2) What is tripe?

3) What are "meat pies"? 
(particularly, I remember several HP canon references to "steak and kidney 
pie" ... what is it?)

4) I'm also puzzled by "beef tea."  Is this like the American "broth," or 
something else entirely?

If any of these appear to be silly questions, please, no flaming.  I'm just asking 
to be more well-informed.  :) 
Thanks!
