Thai fermented rice noodles from scratch step-by-step recipe with photos.
Making noodles from scratch was something I had never imagined I will do. And fermented noodles – I didn’t even know about them until recently. However, of late, we have been more inclined to consume grains in the fermented form. Rice and rotis are often replaced with idli, dosa, and sourdough bread because that is the only form of fermentation I knew. I sometimes make dhokla and handvo which are also fermented foods.
For the past few months, I have been researching on introducing more fermented grain dishes into our diet and came across this amazing recipe of Thai Fermented Rice Noodles.

What is Thai fermented rice noodles
Khanom Chin is fermented rice noodles originating from Thailand that are long, round, elastic, and have a beautiful glaze on them. Its chewy texture, tangy, and nutty flavour is absolutely delicious. Making fully fermented rice noodles is a long process that needs all your patience, and honestly, it is one of the most difficult dishes I have made. But since we do not eat noodles very frequently, it works well for us given I make it once every few weeks.
Also, once you make them, there is no going back to the readymade noodles, at least not for us. I usually serve the noodles with Indo-Chinese dishes to make a complete and delicious meal.
First and second fermentation
First fermentation involves soaking the rice in water for three days. It is important to rinse the rice and refresh the water once a day. Second fermentation involves soaking the rice in brine. The ratio of water to salt is 4 tablespoon salt for one liter of water.
Second fermentation must be done for 2-3 days. Second fermentation does not involve rinsing the rice every day. Do not disturb the rice during second fermentations. Both first and second fermentation takes 5-6 days in total.
Third fermentation
Before doing the third fermentation, the rice starch must be extracted and kept for drying. Grind the rice with a minimal amount of water and let the rice particles settle. Once they settle, place the ground rice in a muslin cloth and put some weight on it so that all the water content is removed from it. This drying process takes 1-2 days and is called the third fermentation.
Making Thai fermented noodles
Before making the noodles, the cream starch needs to be extracted. To do that, steam the dried rice starch and knead it with hot water. Then it needs to be passed through a muslin cloth to remove any gelatinised parts. Use the cream starch to make the noodles. It is also important to rinse the noodles in fresh water.
To conclude
It takes a good 7 or 8 days by the time you get the fruit of your labour. But the best part of making fermented food is that most of the time involved is just wait time, while nature does its magic. I have adopted the original recipe and have tried to make it in a traditional way. It is a learning process and will take a few times to get it right, but totally worth the effort. This recipe is a keeper if you love authentic traditional recipes.
I have explained the recipe with step-by-step pictures for better understanding. Refer to pictures as you read the recipe for better understanding.

Step by step instructions
Soak the rice in water and let it sit for three days - first fermentation (step 1).
Let the rice soak in salt brine for two to three days - second fermentation (step 2).
Grind the rice with minimal water. Let the ground paste sit overnight (steps 3,4).
Pour the ground rice paste onto muslin or cheesecloth (step 5).
Place a heavy weight on top and let it ferment for two days - third fermentation (step 6).

Dried rice starch is ready after the third fermentation (step 7).
Add hot water and knead the rice starch. Keep adding water slowly and knead the rice starch. Rice starch comes together after kneading (steps 8,9).
Place it in fresh muslin or cheesecloth and steam it until it is partially cooked (steps 10,11).
The outer 0.5 cm should be cooked or gelatinised (step 12).

Pound the dough and combine the gelatinised part of the dough with the rest of it (step 13).
Add hot water and knead until the starch is creamy (step 14).
Place the creamy rice starch onto a fresh muslin cloth. Pass the creamy rice starch through the muslin cloth (steps 15,16).
Discard the gelatinous lumps (step 17).
Pour the rice starch into an extruder or chakli press (step 18).

Press the noodles carefully into boiling water (step 19).
The noodles are cooked when it floats (step 20).
Transfer the noodles into cold water. Rinse the noodles three times (steps 21,22).
The noodles are glossy and shiny after rinsing (step 23).
Drain the excess water (step 24).

Fermented rice noodles are ready to be served.


Recipe card

Thai fermented noodles
Ingredients
- 2 cups Rice (I have used sona masoori)
- Water
- Salt
Instructions
FIRST FERMENTATION (3 DAYS)
- Wash the rice thoroughly
- Place the rice in sufficient water to cover it completely
- Cover with a plate
- Let it sit in a dark spot (like inside a cupboard) for three days
- Make sure you wash and refresh the water every day
SECOND FERMENTATION (3 DAYS)
- Add salt to the water and mix well to make brine (you will need 4 tablespoon of salt for every 1 litre of water)
- Wash the rice thoroughly and soak in brine
- Leave the rice undisturbed in a dark spot for the next two to three days
COLLECTING THE RICE STARCH
- Wash the rice thoroughly
- Grind the rice with minimal water (I have used a stone wet grinder to grind the rice. If you don’t have a stone grinder, you can use a blender)
- Pour the ground rice into a vessel. Cover and let it sit overnight in the cupboard. This will help the rice particles to settle
DRYING AND THIRD FERMENTATION (2 DAYS)
- Place muslin or cheesecloth onto a sieve and place the sieve on a large bowl
- Pour the rice mixture onto the set cheesecloth
- Bring all the ends of the cheesecloth together and tie it
- Place a heavy weight onto it, allowing the excess water to drain off (see picture)
- Place it in the cupboard for two days
EXTRACTING THE CREAM STARCH
- Remove the dried starch from the muslin cloth and place in a wide tray
- Slowly add hot water and knead into a dough
- Shape the dough into a ball and wrap it in a fresh muslin cloth
- Place the wrapped dough in a steamer and steam for 4-5 minutes
- Remove the dough from the steamer. It will only be cooked partially at this stage
- Use a spoon to check the thickness of the cooked dough. The outer 0.5 cm should be cooked (gelatinised)
- Place the semi-cooked dough into a wide tray. Pound the dough and combine the gelatinised part of the dough with the rest of it. This must be done while the dough is still hot (refer picture)
- Once the cooked and uncooked dough is combined, add a small amount of hot water and knead it well
- Continue to knead until it reaches a creamy consistency (refer picture)
- Pass the creamy starch into a muslin cloth to remove any gelatinised part of the dough. Discard the gelatinous lumps
MAKING THE NOODLES
- Boil water in a large pot and bring it to a rolling boil. Add a small amount of cold water to remove the air bubbles
- Now swirl the water to create turbulence
- Pour the rice starch into an extruder (chakli press)
- Press carefully onto the hot water laying the noodles into it
- The noodles will initially settle down and when they are cooked, they will float on the wate
- Carefully scoop out the cooked noodles and transfer them to cold water
- Rinse the noodles in fresh, cold water three times
- Remove the noodles from water and lightly press them to remove excess water
- The noodles are ready to be served
