I was amazed that anyone would even think of making a traditional British chutney (as opposed to the fresh ones made in Indian cuisine) so close to the show. I know nothing of kumquats but if they're anything like other citrus fruits this isn't a good time of year for them anyway and it seems perverse not to showcase local produce like apples, plums, pears and so on, all of which make wonderful chutney.
Can't contribute to the French lit conversation, I'm afraid. My French stopped at O level and we never read any real French (as opposed to textbook French). I did struggle through a translation of Therese Raquin (I think that was it) many years ago but found it so depressing I've never made another foray into Zola. I'm ashamed to say I've not even read Madame Bovary.
