I see that December 14 is the newly-created Roast Chestnuts Day.
For me, every time I go to the city of Neuchatel it is roast chestnut day.
For me and many others -- look at the long line of people waiting in the cold to pay several Swiss Francs for a few hundred grams of the nuts!
You can see (especially if you click and enlarge the photo) the silhouette of the man doing the roasting, while an older woman (his wife?) stands at the window of the kiosk weighing, wrapping them in paper, and selling.
Here is my little purchase.
It's also good as a hand-warmer. :)
I always start eating on the tram, because the soft nuts can be peeled so easily, AND THEY ARE SO GOOD!
