Hello Bernard,
I very much enjoy your books, mostly for the historical detail which must take a great deal of research. So I need to query the appearance of sunflowers in abandoned gardens in SW France in 1356. It sounds picky (mostly because it is) but I think sunflowers as we know them today are American natives and it just stuck out at me as an anachronism. I wondered if you meant something else as the food references always seem so careful to be accurate.
Still enjoyed the book though ;-)
Best wishes
Rachel.
