• 08.067 Dream-dinners aren’t any good,

Sometimes we settle for any kind of dinner we can get.  I note here that Tolkien and C.S.Lewis have notably sumptuous descriptions of meals – I’ve heard it said that British authors who survived war rationing have a tendency to do so.  Can anyone link me a good paper on the topic?  Brian Jacques, whose Redwall banquets make my mouth water, was a child in World War II.
