Pickled Spring Onions (Dua Hanh – Vietnamese)

I remember Tet, Lunar New Year, at my grandmother’s house. The air buzzed with anticipation, the scent of incense mingling with the savory aroma of simmering pork. But amidst all the festive dishes, it was the small jar of pickled spring onions that always caught my eye. Their crisp, tangy bite was the perfect foil to the richness of the meat, a little spark of brightness on a plate laden with tradition. Every year, my grandma would make a huge batch. The taste of these onions is one of my strongest memories of Tet celebrations.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 10 minutes
• Total Time: 3 days, 15 minutes (includes pickling time)
• Servings: Varies (Yields 1 large jar)
• Dietary Type: Vegan, Gluten-Free

Ingredients

• 1 lb green onions (white part only)
• 2 cups white rice vinegar
• 2 tablespoons salt
• ½ cup brown sugar
• 5 cloves shallots

Equipment Needed

• Large pot
• Glass jar with lid (sterilized)
• Knife
• Cutting board

Instructions

1. Begin by preparing the green onions. Thoroughly wash the onions under cold, running water. It’s essential to remove any dirt or grit clinging to the bulbs. Once cleaned, spread them out on a clean kitchen towel or paper towels and allow them to dry completely. This step is crucial as excess moisture can affect the pickling process and potentially lead to spoilage.

2. While the onions are drying, prepare the pickling brine. In a large pot, combine the white rice vinegar, brown sugar, and salt. Place the pot over medium-high heat and bring the mixture to a boil, stirring constantly to ensure the sugar and salt dissolve completely. Once boiling, reduce the heat slightly and let the mixture simmer for about 5 minutes, allowing the flavors to meld together. Remove the pot from the heat and let the brine cool completely. It’s important that the brine is cool before pouring it over the onions, as hot liquid can soften them too much.

3. Peel the shallots and slice thinly. Add the sliced shallots into the cooled brine.

4. Now it’s time to assemble the pickled onions. Carefully pack the dried green onions into a sterilized glass jar. Make sure the jar is clean and dry to prevent any contamination.

5. Once the onions are snugly packed in the jar, pour the cooled brine over them, ensuring that the onions are completely submerged. If necessary, use a clean weight (like a small glass or ceramic object) to keep the onions submerged below the surface of the brine. This will help to ensure even pickling and prevent mold growth.

6. Seal the jar tightly with its lid.

7. Let the jar sit at room temperature for at least 3 days. During this time, the onions will slowly pickle and develop their characteristic tangy flavor. For best results, allow them to pickle for up to 5 days, tasting them periodically to check for your preferred level of sourness. Note that longer pickling times will result in a more pronounced flavor.

8. After the desired pickling time has elapsed, transfer the jar to the refrigerator. The cold temperature will slow down the pickling process and help to preserve the onions for a longer period.

Expert Tips & Tricks

• Don’t skip the drying step! Excess moisture is the enemy of good pickles. Thoroughly drying the onions will ensure they retain their crispness and prevent the brine from becoming diluted.
• Sterilize your jar properly: Sterilizing the jar and lid is very important to prevent bacterial growth. You can do this by boiling them in water for 10 minutes, or by running them through a hot cycle in your dishwasher.
• Adjust the sweetness: If you prefer a less sweet pickle, reduce the amount of brown sugar slightly. Conversely, if you like a sweeter pickle, add a tablespoon or two more.
• Experiment with flavors: While this recipe calls for shallots, you can also add other aromatics to the brine, such as garlic cloves, chili peppers, or ginger slices.
• If you notice any mold or unusual smells, discard the entire batch.

Serving & Storage Suggestions

Pickled spring onions are best served chilled. They make a fantastic accompaniment to rich, fatty dishes, such as roasted pork belly, braised meats, or even grilled fish. They can also be added to salads, sandwiches, or noodle bowls for a tangy kick.

Store the pickled onions in the refrigerator for up to 3 weeks. Be sure to keep them submerged in the brine to prevent them from drying out. While freezing is not recommended, the onions can last for several weeks if properly stored in the fridge.

FAQs (Frequently Asked Questions)

Q: Can I use other types of onions for this recipe?

A: While this recipe is specifically for spring onions (the white part), you could experiment with other mild onions like pearl onions or even very young leeks. Keep in mind that the flavor will differ slightly.

Q: How long do the pickled onions last?

A: When stored properly in the refrigerator, pickled spring onions will typically last for up to 3 weeks. Always check for any signs of spoilage before consuming.

Q: Can I reuse the pickling brine?

A: It is generally not recommended to reuse pickling brine, as it can harbor bacteria and may not provide the same level of acidity for proper preservation.

Q: Do I need to use a special type of jar?

A: A sterilized glass jar with a tight-fitting lid is essential for successful pickling. Mason jars or other canning jars are ideal.

Q: My pickled onions are slimy. What did I do wrong?
