The Christmas log A culinary tradition for the end of the year

The log is a cake with which the Christmas or New Year's meal in Luxembourg comes to an end. Its origin is linked to a rite celebrated at the winter solstice. On the longest night of the year, a huge log was burned. This custom has existed since the Middle Ages and was spread throughout Europe. Today, it is mainly the sweet tooth that "burns" for the delicacy. The Luxembourg School of Hotel Management and Tourism (École d'Hôtellerie et de Tourisme du Luxembourg) offers you two recipes to make your own: the classic and the vegan one!


The Luxembourg Hotel and Tourism School is the only establishment in the Grand Duchy to offer full-time training in the hotel and catering industry and education in the field of tourism. The school, located in Diekirch, focuses on the relational and behavioural skills of the hospitality industry. The young graduates therefore benefit from professional skills and personal qualities in their future profession. A recipe for success!
