In Bhutan, buckwheat (Fagopyrum esculentum) is grown in non-rice growing regions and highland areas where cultivating other cereals is limited due to agro-geo-climate variations. Buckwheat is used throughout Bhutan in myriad culinary preparations, and of these, puta, a buckwheat noodle from the Bumthang Dzongkhag (Bumthang District), is very popular.
