You're right, Helen, about the mutton. Although hardly anyone eats it any more, it was de rigueur for Sunday dinner in England in Victorian times, and was usually referred to as "the joint". John Galsworthy, in The Forsyte Saga has a passage about how the various senior Forsytes all had differing views about what was the best mutton. One of them even earned the contempt of all the others for having the temerity to express a preference for New Zealand mutton!
