The noodles are still pressed by hand through a wooden tool called a puta-par, a method locals trace back to at least the early 1500s, when it turns up in the biography of the Bhutanese saint Pema Lingpa.
Buckwheat dough is forced through a wooden press directly into boiling water, then the noodles are drained and pan-fried with butter, onion, and chili until they pick up a nutty, faintly bitter flavor. Bumthang's market stalls and farmhouse kitchens serve it as a filling everyday plate, no rice required.
