Dồ Chua (Vietnamese Pickled Daikon and Carrot) - Strips of daikon (Asian white radish) and carrot are pickled in sweet and sour brine. Do Chua is a staple condiment in Vietnamese cuisine. 
I’m never a fan of salty sour pickles, but if you give me sweet and sour pickles, like this do chua, I absolutely love them. I don’t consider myself having a sweet tooth, but I like my pickles to have that sweetness. Just like this Acar Timun I made a while ago, I absolutely like the cucumbers being pickled this way.
DO CHUA (VIETNAMESE PICKLED DAIKON AND CARROT) What in the world is daikon you might wonder at first. Daikon is a large white radish, typically used in Asian cuisine. Sometimes also known as oriental radish or Chinese radish. Daikon is also referred to as turnip or carrot in Singapore. Whey they say carrot cake in Singapore, they mean this Kue lobak / Chai tow kway (Chinese savory daikon / turnip cake) Daikon and carrot are the main ingredients in this Vietnamese do chua. They are both pickled in acidic, sweet, and sometimes spicy brine. Majority of the work, if you ask me, lies on cutting the daikon and carrot into strips. Of course you can always shred them shredder too.
RATIO OF DAIKON AND CARROT IN DO CHUA How much of daikon and carrot in do chua really depends on your preference. Some people like 1:1 ratio, meaning the same amount of daikon and carrot. I like it more daikon than carrot. To me, the carrot is more for pleasing the eye. The nice vibrant orange against the pale daikon. So, it’s really up to you.

TIPS FOR MAKING DO CHUA 1. Draw the water out The daikon and carrot will be treated with salt to draw water out from them before being pickled. This step is important as the vegetables will remain crunchy for longer time 2. Pickle for at least 24 hours Some people will tell you that you need at least 48 hours before you can serve the pickle. When I feel like it does taste the best at 48 hours, when I tasted it at 24 hours, the do chua actually taste decent too. So, if you are pressed for time, I would say you can use it at 24 hours, not anything sooner than that though

PUNGENT SMELL OF DO CHUA I have to warn you though that the longer the do chua being pickled, the pungent the smell gonna get. It is all because of the daikon and really, nothing is wrong with your do chua. It hasn’t gone bad or wrong! It’s just the nature of daikon. Before serving, you can open the lid of the jar and let the smell “out” a bit before serving if you that really bothers you. The do chua itself doesn’t taste like it smells. I promise!
