Soak the onions
First, prepare a bowl of water, add 100g of salt and 1 teaspoon of alum, then immerse the onions in the water for about 12 hours (or overnight).
After that, take the onions out and rinse them thoroughly with water.
Tip
- You can replace the alum saltwater with rice washing water, lye water mixed with salt, or clear lime water.
- Soaking the onions in saline water overnight helps remove dirt, reduces the pungent smell, and makes the onions crisper and tastier.
-
Cut the onions
After rinsing, take the onions and cut off the roots, tips, and the outer layer, then place them on a tray or basket to drain thoroughly.
Note: To prevent the onions from absorbing water and losing their crispness, only cut off the roots and do not cut too deeply into the body of the onions.
-
Marinate and dry shallots
After preparing the shallots, place them in a bowl and add 300g of sugar, then mix well.
Spread the shallots evenly on a tray and dry them in the shade for about 3 – 4 hours until they become firm.
Note:
- To ensure the sugar is absorbed evenly into the shallots, you should frequently stir them while drying.
- Avoid drying the shallots in direct sunlight, as this can cause them to become overly dry, which will affect the taste when pickled.
- To reduce dust, you should cover the shallots with a thin cloth or mosquito net while drying.
-
Prepare the pickling solution
Place a pot on the stove, add 500ml of vinegar, 100g of sugar, and 1 teaspoon of salt, then bring to a boil. Once the sugar has completely dissolved, turn off the heat and let it cool.
Tip: To enhance the flavor of the dish, you should use fermented vinegar for pickling the shallots.
-
Pickle the sweet and sour shallots
Once the pickling solution has cooled, pour it into a jar containing the prepared shallots and cover it. Let it sit for about 2 – 3 days at room temperature before serving.
Note: To ensure the glass jar is clean and free of impurities, you should wash it thoroughly with water and rinse it with boiling water.

How to choose delicious pickled onions
- Currently, there are two main types of onions on the market: Hue onions (cinnamon onions) and buffalo onions. To match the sweet and sour pickled onions dish, you should choose Hue onions, characterized by a swollen body, quite large bulbs, many roots, thin leaves, a narrow waist, a clear waistband, and a strong pungent taste.
- Choose onions that are of moderate and uniform size, still fresh and green, without being bruised or showing signs of mold.
How to store pickled onions
- Usually, onions soaked in vinegar, salt, and sugar like this can be stored for a long time. However, the longer they are kept at room temperature, the more sour they will become, so once the onions are ready to eat, you should keep them in the refrigerator to prolong their freshness.
- Use clean, dry chopsticks to take out the onions. Do not use chopsticks that are greasy or have food residue on them to pick up the onions, as this will spoil the onions in the jar.
- If you take out the onions onto a plate and do not finish them, you can cover them with plastic wrap and store them in the refrigerator, and do not pour them back into the jar to avoid transferring grease when eating, which can spoil the onions in the jar.
