Mac khen, an indispensable spice of ethnic groups in the northwestern region
In Muong language, the name of mac khen is rather self-explanatory, describing the pungent, peppery smell of the spice. However, its fragrance compound is far more complex than pepper with an additional crisp, dry woodiness woven into green citruses. This makes mac khen a truly versatile spice that can elevate any dish, said Nga.

The first Cultural, Sports and Tourism Festival opened in the northern mountainous province of Lai Chau on October 13, in response to the Lao Cai – Northwest National Tourism Year.
