Vietnamese Preserved Lemons & Salty Lemonade (Chanh Muối)

If you have plenty of lemons (or limes), you can preserve them in a salty brine that will keep for eternity. That’s exactly what I did when I rummaged through my sister’s backyard and looted her lemon tree.

It’s typical to see dusty jars of preserved lemons and limes in a Vietnamese household. The dustier the jar, the older the folks who made it. I am now on that level with two dusty jars of my own.

What is Chanh Muối?

In Vietnam, we called lemons preserved in a salty brine Chanh Muoi and the refreshing iced drink made with them, Nuoc Chanh Muoi.

What is Nước Chanh Muối?

Nuoc Chanh Muoi is the drink made with preserved lemons. It’s a mixture of preserved lemons, ice, sugar, and water. Sometimes carbonated/soda water is used instead, called Soda Chanh Muối.

This Vietnamese drink is similar to lemonade but salty, as you would expect from a salty brine. If you enjoy a salty note with something sweet, you will definitely love this drink. You’ll just have to wait at least two months to enjoy it. Ha!

Luckily for you, you can find these on the drink menu at Vietnamese restaurants for a more immediate treat.

For those who want to make this at home, check out my video recipe above. I’ll walk you through how to preserve the lemons and how to make the popular refreshing drink from start to finish.

  1. do i have to wait a year before my preserved lemons turn brown b/c mine are just a less vibrant yellow and its been months?

    1. It’s usually ready in two months but the longer, the better.

  2. Hi! Just tried this a few days ago, and my limes are starting to emit gases so there is fizz building up and I tried to open it today and it gave a big burp. Do I not have enough salt in the brine?

  3. This is perfect! Recently my favorite local place stopped serving their salty lemonade and I have had a mighty need for it!! I immediately sent this to my sister! Thank you so much

  4. Hello! I am looking forward to trying this recipe but I wanted to ask about the fermenting process. During the first two months, does the jar need to be opened or burped at all? I’ve only ever fermented once before and it was pickles and I used a pickle pipe to release gasses. I want to make sure I’m not doing something wrong to cause my jar to shatter.

    1. Hi there. No, I didn’t need to open the jar to release any build up gas.

  5. Hello, once all the original lemons have been used can new lemons be added to the brine?

    1. Yes you can.

  6. Hi! This looks like a really neat recipe. It’ll be my first time making this. Have you tried using limes and how does the taste compare to the lemon chanh muoi? Thank you!

    1. Yes, any citrus will work. Limes are great too.

      1. Awesome, thanks for the reply! Can’t wait to try making both versions 🙂

  7. Hi, my mom leaves her jar in a sunny spot but one of her jars has grown mold. I told her she should probably throw it away but instead she just scoops out the mold and makes herself a cup like usual. I don’t know much about Chanh muoi and usually avoid it since the existence of mold in the same jar she drinks from kind of grosses me out, so I wanted to ask an experts opinion! The jar has grown mold since maybe 5-6 months after it’s making, but I think it’s existed for the past 2-3 years

    1. Hi Vanessa, your mom is right. This is what I do too. Once in a while, I would see white mold (not black mold)…a little speck here and there. I too would just scoop it out with the surrounding water and discard. The rest of the chanh muoi is safe and I never had any problems. Many people I know also do the same.

      1. You are right. White mold is Kamm mold and harmless. It usually happens when a brine ferment is exposed to air. Black mold is BAD. It should not happen if you have enough salt in your brine.

        I will try this Chanh Muối recipe. I tried some recently and loved it. Hopefully mine will be good.

  8. I made some about a year ago and they have been great. I pulled a half jar down today and the limes have some gelatinous bits around the bottom. Is that ok?

    1. Hmm, it could be that the lemons raptured and the inside bits are floating around. Happens to me sometimes when I push down too hard to keep the lemons submerged. But to be sure, I’d rinse the gelatinous bits away before using.

  9. Forgot to ask…: how long is the shelf life ?

    1. Mine is close to a year now and still going strong. I’m ready to start this year’s batch 😃

      1. Hey, my brine got all jelly. Does this happen normally? Or can I fix it?

      2. Hi Lily, the brine thickened to a jelly consistency? Sorry, that has never happened to me before. Depending on how long it has been, you might be able to reuse the lemons and start the brine over. It shouldn’t thicken.

  10. My lemons from my tree is finally ready! And I just ordered the glass container you linked. Question is : how long do you have it sitting in a sunny spot,? The whole two months? Also after opening how do you store the jar of preserve ?

    1. Hi Phuong. Yes, I leave the container directly in the sun for the whole two months to get it going and move it to a sunny spot like my window sill after opening. The lemons will continue to preserve in the jar. Just make sure it’s also submerged in the brine in a sunny spot. Use weights if needed. I have the same jar close to a year now. Still very delicious.
