The Galette de Rois is a traditional French cake made for the Epiphany on January 6 (The Epiphany is the manifestation of Jesus to the Magi. Feast of the Church which recalls this event.). On this day, three magi, in France they are called three wise men, from where the name of the cake, Balthazar, Melchior and Gaspard brought gifts to the little Jesus, gold, incense and myrrh. The classic version of this cake is made of frangipane (mixture of pastry cream and almond) and puff pastry.
There is no such tradition in Belarus, and no one knows it. I tried to make this pancake at home and tell my family about it! I’m happy with the result, not perfect of course, but it’s a homemade oven and manual rolling, especially at the start! My family loved it.
