Yesterday, people in France were celebrating by eating the Galette des Rois. The galette is a puff pastry pie filled with frangipane, which itself if a pastry cream made with ground almonds, cream and eggs. The celebration became over time secular to some extent, although it takes its roots in the Epiphany, a Christian feast which holds different meanings for the various groups of Christians.
The galette contains a hidden bean, nowadays not a real one but a ceramic figure, most of the time a religious, Christian one, although all kinds of modern figures are also issued to please children, collectors and non-Christians. The cake comes with one or two golden paper crowns. The person who finds the bean in their slice becomes King or Queen. They can then pick a person to become their consort, who gets the second crown. It is a fun opportunity to have a family get-together usually welcomed by both children and adults.
I have seen recipes in my area for a chestnut galette but have never tried to make one. Maybe next year!
