With your partner, write a nice blog entry on the history
of the word you've picked. Remember to check the OED online.
But don't just use online references (in fact, I suspect
most online etymologies are just made up).
Instead, use references such
as the Cambridge World History of Food, the Oxford Companion to Food,
The Larousse Gastronomique, individual cuisine histories like Kate Colquhoun's "Taste: The Store of Britain Through Its Cooking", or spice histories like
Andrew Dalby's "Dangerous Tastes: The store of spices".
