Guthuk
Guthuk ༼དགུ་ཐུག་༽ is a noodle soup in Tibetan cuisine. It is eaten before Losar, the Tibetan New Year and is a variation on Thukpa bhatuk. The Tibetan religious ceremony 'Gutor' ༼དགུ་གཏོར་༽, literally meaning offering of the 29th, is held on the 29th of the 12th Tibetan month, and is focused on driving out all negativity, including evil spirits and misfortunes of the past year, and starting the new year in a peaceful and auspicious way. It is made with barley.
