1. Why is Quang Binh's chewy dried sweet potato so famous?

Though the name might sound unfamiliar, khoai deo is a familiar dish tied to generations of Quang Binh locals. Made from fresh red sweet potatoes grown on white coastal sand dunes, through the skillful hands and patience of the locals, they become fragrant, sweet, and chewy slices of sweet potato, carrying within them the flavors of sun, wind, and hard work. 

Special Ingredient

Red sweet potatoes grown in the sandy loam soil of Quang Binh are said to have a distinctive flavor, being chewier and sweeter than sweet potatoes grown in other regions.

Elaborate Preparation Process

To create authentic and delicious batches of khoai deo, locals must go through many meticulous steps:

  • Selecting sweet potatoes: Fresh red sweet potatoes, free from pests and diseases, harvested at just the right maturity.
  • Boiling: Sweet potatoes are boiled just until done to preserve their natural sweetness.
  • Slicing: Sweet potatoes are sliced into thin pieces longitudinally.
  • Sun-drying: This is the most important step; the sweet potatoes are dried under the intense Central Vietnam sun for 10-12 days on woven mats lined with a layer of "rười" plants (a plant growing on sand dunes) to prevent sticking.
  • Drying to perfection ("Deo"): After receiving enough sunlight, the slices shrink, turn a beautiful amber-brown color, and achieve an ideal chewy texture.

Unique Flavor

Quang Binh khoai deo has a naturally subtle honey-like sweetness, malt-like chewiness, and the signature rich aroma of sweet potatoes. When enjoying it, one can feel both the salty breeze of the sea and the harshness of the climate here.

Cultural Value

Khoai deo is not just a food item, but also a part of the culinary culture of Quang Binh people. It is a simple gift from the countryside, filled with affection and appreciation for the produce of their homeland.

Enjoying a piece of khoai deo while sipping a cup of green tea, you will fully experience the authentic flavor of the land of Lao winds. 

2. Enjoying chewy dried sweet potato the right way

It is no coincidence that khoai deo is considered the 'soul of Quang Binh specialties'. Each small slice, with its glossy reddish-brown color, yields a subtle sweetness and soft chewy texture that spreads across the palate when chewed slowly. The deliciousness of khoai deo comes not only from its natural sweetness, but also from a meticulous preparation process: from selecting the finest sweet potato varieties and boiling them to just the right degree, to drying them under the sun for several days on traditional bamboo mats to achieve perfect chewiness.

To enjoy khoai deo authentically, savor each piece in the afternoon alongside a cup of hot tea or rich coffee. The nutty taste and sweet lingering aftertaste of the sweet potato blend with the rustic aroma, making it unforgettable. This is not only a healthy snack, but also a piece of hometown memory for Quang Binh people living far from home.
