“Củ Lùn”: A Tasty Treat from Vietnam’s Mekong Delta

In Vietnam, especially in the southwestern provinces where the climate and soil conditions are favorable, “củ lùn” (dwarf lily bulbs) are widely cultivated. With only one harvest per year, starting from the 11th or 12th lunar month and sometimes lasting until the next year’s first or second month, these bulbs are a delicacy.

Beyond its refreshing, crisp, and sweet taste, the “củ lùn” is prized for its nutritional value. In traditional medicine, it is believed to possess cooling properties, aiding in detoxification, digestion, and diuresis. Packed with dietary fiber, this bulb also improves gut function, prevents constipation, and suits those on a diet. Additionally, the “củ lùn” contains easily digestible starch, vitamin B complex, and essential minerals, making it an ideal choice for those seeking nourishment without overheating the body.

Known by various names such as “củ năng tàu” or “củ sâm lùn,” the “củ lùn” is a specialty in the Mekong Delta. Its unique shape gives it away, as suggested by its names.

In the past, “củ lùn” was not widely sold as farmers grew it in small quantities. With only one harvest per year, its availability was limited. It was typically reserved for special occasions during the Lunar New Year or when honored guests visited. Locals in the Mekong Delta often steamed “củ lùn” as a snack, dipping it in salted chili lime or coconut cream, or cooking it in a soup with shrimp and minced pork. The natural sweetness of the bulb blends beautifully with the richness of the broth, creating a rustic yet captivating dish.

To preserve its crispness and nutritional value, “củ lùn” must be processed immediately after harvest. The stems are removed, and the bulbs are thoroughly washed and steamed for 10-15 minutes, transforming them into a delicious delicacy from the lush gardens of the Mekong Delta.

Thanks to the interest of urban consumers, “củ lùn” is now a promising crop in several Mekong Delta provinces, including An Giang, Tien Giang, Dong Thap, and Can Tho. Many farming households have boldly expanded their cultivation areas, embracing organic farming practices to establish stable supply sources for the market. With increasing production and the allure of its unique name and distinct flavor, “củ lùn” is gradually winning over even the most discerning palates.

Despite its humble appearance and unusual name, “củ lùn” is a culinary gem in the Mekong Delta, offering a range of rustic yet captivating dishes. Whether steamed, boiled, cooked in soup, or stir-fried, each preparation method imparts a distinct flavor, ensuring that visitors will remember the taste long after their journey.

When visiting Vietnam’s Mekong Delta, be sure to indulge in the region’s unique “củ lùn” specialties.

Steamed “củ lùn” in coconut water is a simple yet memorable dish. The bulbs are carefully cleaned and steamed with fresh coconut water, resulting in a tender texture infused with the creamy richness of coconut. It’s a dish that strikes a perfect balance between sweetness and freshness.

Once considered a food to ward off hunger during scarce times, “củ lùn” has now become a prized ingredient in various specialty dishes, such as “củ lùn” dessert soup, chicken braised with “củ lùn,” and boiled “củ lùn.”

Another popular choice is the “củ lùn” and shrimp soup. The bulbs are peeled, cut into bite-sized pieces, and cooked with freshly pounded river shrimp. The clear broth, sweetened by the fresh shrimp, is complemented by the distinctive crunchy texture of the bulbs. This soup is not only delicious but also helps to cool the body, making it ideal for hot summer days. Some families add a few slices of ginger or chopped scallions to enhance the flavor.

For those who prefer a bolder, savory flavor, stir-fried “củ lùn” with three-layer pork is a must-try. The bulbs are parboiled to retain their crispness and then stir-fried with thinly sliced pork belly, seasoned with fish sauce, shallots, and a hint of pepper. The natural sweetness of the “củ lùn” blends beautifully with the fatty richness of the pork, creating a harmonious dish that elevates even the simplest rice meal.

“Củ lùn” dessert soup: a refreshing, mildly sweet treat.

The “củ lùn” dessert soup is a humble yet beloved treat among the locals in the Mekong Delta. Slices of crisp “củ lùn,” sweetened with coconut milk and a touch of palm sugar or pandan leaves for a subtle fragrance, create a delightful combination. This dessert not only cools you down during hot summer days but also leaves a pleasant, nutty aftertaste. Despite its simplicity and modest ingredients, the “củ lùn” dessert soup remains a favorite at family gatherings and familiar sidewalk cafes.

From an obscure vegetable to a newfound culinary icon, “củ lùn” has earned its place as a signature delicacy of the Mekong Delta. It is a taste of the region that visitors are encouraged to experience when exploring the charming landscapes and unique culture of southwestern Vietnam.
