Terry Pratchett and Neil Gaiman's Good Omens is set in England, and one of the characters is Madame Tracy, who makes her living by doing "occult" seances, either by using a crystal ball or a Tarot deck (which doesn't contain any Major Arcana because their sight was upsetting the clients). The following detail caught my attention:
And she made sure that she had always put sprouts on to boil just before a seance. Nothing is more reassuring, nothing is more true to the comfortable spirit of English occultism, than the smell of Brussels sprouts cooking in the next room.
Is this some sort of British humour? From an Internet search I can see that Brussels sprouts seem to be an (in)famous popular Christmas dish in Britain - is that it? The novel isn't set during Christmas, though; the Annotated Pratchett File and this reference file by Tor.com don't mention this scene.
