For Northern and central Europeans, December 6th is St. Nicholas Day, and St. Nicholas Day is the chocolate holiday.
It's admittedly a kid's holiday. Ostensibly, you're meant to polish your own shoe and leave something out for him to eat. But in our house, it has perversely turned into St. Nicholas finding his own way to the fridge, the shoe cupboard (notice how he found my most fanciful outrageously colourful ones), and getting treats for adults. I just get to come downstairs and find them. This year, Neuhaus, all crème fraîche fillings. R. must have told him what I like.
