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.
