The charm of pickled cucumbers from the Mekong Delta lies in the harmonious blend of mild sourness from pickled cucumbers and the salty-sweetness from fish sauce, sugar, and spices. When savored, the eater perceives a crisp, sour, spicy, and sweet fusion, offering a familiar yet enticing sensation. Consequently, pickled cucumbers frequently grace family meals, especially when accompanied by white rice, braised fish, or rolled dishes, as they perfectly complement these dishes.

To prepare authentic pickled cucumbers, people from the Mekong Delta often choose either cucumbers or bitter melons. Depending on individual preferences and customs, both types can offer distinct delicious flavors. Bitter melons usually require a longer pickling time than cucumbers, but both can retain their crispness if properly processed.
The basic ingredients include 3–4 cucumbers or bitter melons, garlic, chili, ginger, and optionally carrots for added color. Essential seasonings comprise salt, brown sugar, rock sugar, vinegar, fish sauce, and a cup of rice water that has been refrigerated overnight. The rice water is the secret to the mild fragrance and enhanced natural sweetness of the pickled cucumbers.
After thoroughly washing the cucumbers, quarter them lengthwise, discarding the seeds but retaining the skin. Subsequently, rinse them again and let them air dry. Prepare the brine by boiling approximately 1.5 liters of water with a tablespoon of salt for 5 minutes; let it cool down and then use it to soak the cucumbers. Tidyly arrange the cucumbers in a clean glass jar, adding the cooled brine, rice water, and half a cup of filtered water. For optimal quality, ensure the jar is clean, weighted down to keep the cucumbers submerged, tightly sealed, and stored in a cool, ventilated area for 3–4 days.
Once the cucumbers have been brined for the designated period, remove them, rinse them with boiled and cooled water, drain them, and cut them into bite-sized pieces. Toss the cucumbers with a mixture of brown sugar syrup and filtered water, allowing it to cool before use. Adding a spoonful of rock sugar lends a delicate sweetness, enhances the color, and makes the cucumbers crisper. This step is crucial as it determines the distinctive flavor of the dish. Let the cucumbers marinate for at least 4–5 hours to absorb the sugar thoroughly.
For an extra special touch of fragrance, toasted rice can be blended in. This step is optional, as many people prefer their cucumbers without it, yet it adds a nutty aroma and a subtle fatty taste, enriching the overall flavor profile.
The accompanying fish sauce dip is crafted from a blend of crushed garlic and chili, seasoned with sugar, lime juice, and premium fish sauce. This sauce strikes a perfect balance of spiciness, saltiness, sweetness, and sourness, and when combined with the sweetened cucumbers, it creates a delightful symphony of flavors. Finally, garnish with thinly sliced red chili peppers for an extra touch of allure.
