One of the staples my mom and grandma kept in the kitchen was dưa chua, or pickled mustard greens. It was often served as a side dish for meals throughout the day. These pickled greens counter-balance many salty dishes such as thịt kho. Northern Vietnamese more commonly eat this with thịt đông.
I remember seeing a plate of this at meals quite often as a child, much before I mustered up the courage to try đồ chua. These pickles are less pungent and have a variety of textures and crunch making them fun to eat. Some of my relatives only like the leaves, and some only like the crunchier branches. So depending on who visited more during the week, the big jar of do chua would be imbalanced like a marshmallow-stripped cereal box.
Whether your preference for do chua is for leaves or for the stems, you can start by choosing a fitting head of gai choy. 1.5 to 2lb. heads make a good amount for me. Younger (smaller) ones aren’t as crunchy. Older (larger) ones have more stem than leaves.
Break apart the leaves and wash all the dirt off under running water. Shake off excess water and lay out on trays to dry. We do this so the final result is crunchier and slightly chewier. Find a balance of drying time that you like. This drying process also helps make your dưa chua last longer since we remove water from the leaves and replace it during pickling with saltier water.
They can be left out overnight in the kitchen for more time drying. This processed can be sped up by sun drying.
After a day of drying, chop up the mustard greens and yellow onion into whatever size you like.
After the water has boiled and cooled to touch, add everything to the pot. You can transfer to a jar at this point too. It can be glass or plastic, with a rubber seal or just a plastic screw on lid. Old kim chi jars are perfect for this. I recently found out some shops nearby that occasionally sell used (and washed) kim chi jars for under $1.
Place in a warm place. This can be next to a window, heater vent, or in the oven with the oven light on. Check on your dưa chua every day or so to see how sour it gets. It can be anywhere from 1-4 days depending on the room temperature. When it gets sour enough to your liking, move the jar to the fridge.

- Combine water, salt, sugar, and vinegar in a pot and bring almost to a boil. Turn off heat and wait until water cools. It should be hot, but you can touch it without burning yourself.
- Add all the vegetables into the pot, making sure everything is submerged. You can also add all of this into a jar instead of the pot. Leave your container in a warm place (window sill, or oven with the oven light on) so it can pickle. Taste a piece every 24 hours until it gets sour enough for your taste, then transfer to the fridge.
