>>-- the term 'slab' is used for both beer and chocolate, and also for concrete (which nobody has mentioned yet, probably because it's not digestible!) -- and now also bacon!

We should be able to link up soon with the long-running 'bread rolls' thread!<<

Well, paulb--so far at your party, we're having haggis, bacon, and souse, innumerable kinds of bread, washed down
with beer, and with chocolate for dessert. Sounds okay
so far, except I don't like beer--got any iced tea? (Yes, I
drink it in winter.)
We use the phrase slab of concrete here, too.
