Upon my Heinz pickle pin (which they'll give you for free at the museum if you ask) I spent many years being baffled by the phrase "redd up" until I found it used in the same manner in Robert Louis Stevenson's KIDNAPPED.

Why this Scottish locution continues in use in Pittsburgh is beyond me. Did the Scots-Irish who came north to work in the mills bring it with them? If so, why is it unknown in the South?

I asked a friend about Salad Cream, and she said, "Don't you know? You can get it in the British section at Fairway." I hied myself to Broadway and 73rd, and there it was. Didn't buy any, but it seems to be sort of a mayo with mustard.
