Perhaps you’ve heard of xôi khúc and bánh khúc—traditional Vietnamese dishes. But do you know the key ingredient that makes these dishes so unique and delicious? It’s a vegetable called rau khúc (or ngách in some dialects). In this article, we’ll explore the origins of this vegetable, its nutritional benefits, and how it can be used in cooking to create some truly special dishes.

1 What is Rau Khúc?

Rau khúc, or ngách, is a leafy green vegetable that goes by many names, including khúc nếp, khúc tẻ, and rau khúc vàng. Its scientific name is Gnaphalium uliginosum, and it belongs to the Asteraceae family, also known as the Compositae family, which includes other well-known flowers such as marigolds and chrysanthemums.

Rau khúc thrives in temperate and subtropical climates and is commonly found growing wild in damp areas, such as along roadsides, lakes, ditches, and rice fields. It has a bushy appearance and can grow up to 50 cm in height.

What is Rau Khúc?

As a herbaceous plant, various parts of rau khúc are used medicinally, and its leaves are used in cooking to add a unique flavor to dishes like bánh and xôi. There are two main varieties of rau khúc: nếp and tẻ. The leaves of rau khúc nếp are larger and a darker shade of green, similar to Chinese mustard greens. Rau khúc tẻ, on the other hand, has smaller leaves with white spots and white flowers. When used in baking, rau khúc nếp tends to produce a crumbly and slightly bitter dough.

Due to its rarity, rau khúc can be quite expensive, with prices ranging from 45,000 to 50,000 VND per 100 grams on e-commerce platforms, equivalent to approximately 500,000 VND per kilogram.
