“It is easier to ship recipes than cakes and biscuits” — a quote attributed to John Maynard Keynes since June 2013 (http://www.architecture00.net/news/2206) at least 2008 (https://books.google.nl/books?id=2pV9Geqv1cIC&pg=PA211#v=onepage&q&f=false). Seems an unlikely Keynes quote, as the Keynesian “cake” typically is the economy.
