If you've been following along for any length of time, you probably know I've been working on concocting the perfect bowl of ramen for quite some time. With the soup improving with each batch I made, I was starting to feel like the store-bought noodles were the weak link holding the entire bowl of ramen back. It was time to tackle the noodles, but given the decade of trial-and-error it took to get the soup right, I figured I was in for another dozen years of experimentation before I'd turn out a decent batch of homemade ramen noodles.
Part of the problem is that there isn't much information out there in English on making ramen noodes. Even in Japan, noodle making is a closely guarded secret and you don't see ramen shops parading around their recipes on the web. From the information I was able to glean, I knew that the noodles are made with wheat flour, and get their yellow color and distinctly firm texture from the addition of kansui. I also knew that they're traditionally hand pulled, which means the dough has a higher water content than noodles you'd roll and cut.
Since noodles get their texture from the proteins in the wheat forming elastic chains of gluten, I decided to use bread flour, which typically contains 12-14% protein (higher than all-purpose flour). I also knew that learning how to hand pull noodles as fine as ramen was a skill that would take far longer to master than I, or many of my readers, would have patience for, so I decided to make a drier dough that could be rolled and cut using a pasta maker. This would put homemade ramen noodles within the reach of most home cooks.

Here's an account of my learnings batch by batch:
Batch #1: I made this with 2 cups bread flour, ⅔ C water and ½ teaspoon of liquid kansui. Everything went into a stand mixer with a dough hook until the dough came together. Then I formed it into two squares, wrapped and refrigerated one, and rolled out the other. I rolled it out to setting #5 of on the pasta maker and cut it using the spaghetti attachment, then boiled the noodles for 1 ½ minutes. This batch had a couple of problems. The dough was a bit tacky, so even after being dusted with flour, the noodles stuck together in pairs of two and had to be hand separated. I'd also rolled it out too thin and by the time the noodles were in the ramen, they were soggy. The dough also lacked the lustrous yellow color I was looking for. Fresh noodles, but not quite what I was looking for.
Batch #2: After resting in the fridge overnight, I took the other half of the first batch and rolled it out, this time only to setting #3. The strands were still sticking together, but the noodles had a nice firm texture when cooked.
Batch #3: For this batch, I used 2 cups of bread flour, reduced the water to ½ cup and increased the kansui to 1 teaspoon. As soon as I added the water/kansui mixture I knew this batch was going to be better, as the flour immediately turned a bright golden yellow. I let the mixer run for 10 minutes this time and the mixer bowl was full of golden yellow nuggets. I was worried I hadn't added enough water, but with a little hand kneading it came together into a ball, and I let this rest overnight in the fridge. The next day, I cut the dough in half, rolled it out to setting #3 and ran it through the spaghetti cutter as before. This time the noodles didn't stick together, and I reduced the boiling time to just over a minute. The noodles were extremely firm (almost too firm), but by the time I had the soup and all the toppings on the ramen, they were the perfect texture and stayed that way until the last drop of soup was gone. Success! Homemade ramen noodles that came very close to store-bought.

If you're wondering what kansui is, it's the ingredient that makes all the magic happen. The story goes that the unique noodles produced around lake Kan in Inner-Mongolia were attributed to the water from the lake. Modern science has since revealed that the lake is highly alkaline, which is what gives the noodles their unique texture, flavor, and color. You can now buy factory produced "kansui" (lake Kan water) either in powdered or liquid form. I used a brand called Koon Chun which labels their product as Potassium Carbonate Sodium Bi-Carbonate. It's similar to lye water used in European baking, but check the label to be certain it has the same composition.
If you're looking for a more scientific explanation behind how kansui works, here's what Dr. Kantha Shelke, Scientist at Corvus Blue LLC, a Chicago-based food and nutrition research firm has to say:
Science Behind the Noodle
"Kansui is a mixture of sodium carbonate and potassium carbonate which form an alkaline solution (pH ~9) when mixed with water. Wheat flour contains a number of compounds called flavones and trans-ferulic acid which are bound to starch and therefore colorless or white. The addition of an alkaline solution to wheat flour changes the pH of the mixture, which in turn detaches these flavones (specifically apigenin glycosides) and trans-ferulic acid from starch and allows their natural yellow color to manifest.
"Another reason for the addition of kansui is to toughen the protein in wheat flour so that the resulting noodles are firmer, more elastic and springy texture, and less sticky when cooked. The addition of Kansui allows the use of lower protein (and therefore less expensive) wheat flour to make noodles with the quality one would expect of noodles made with superior quality flour with higher protein levels."

I know this isn't a typical post since you don't end up with a finished dish, but I really wanted to write a comprehensive post on making ramen noodles from scratch. Here are some recipes for ramen and ramyeon that you can use these alkaline noodles for:
- Tonkotsu Ramen (Pork Ramen)
- Hokkaido Miso Ramen
- Tsukemen Ramen (Dipping Ramen)
- Chicken Ramen
- Kimchi Ramyeon (Korean style ramen)
- Tonkotsu Miso Ramen
- Spicy Tantanmen Ramen
📖 Recipe

Units
Ingredients
- 300 grams bread flour (about 2 cups)
- ½ cup water warm
- 1 teaspoon kansui (Potassium Carbonate & Sodium Bi-Carbonate)
Instructions
- Put the 300 grams bread flour in the bowl of a mixer fitted with a dough hook. Mix the ½ cup water and 1 teaspoon kansui together, then add the mixture to the flour. The flour should immediately start turning yellow. If it doesn't, it's possible your kansui is less concentrated than the one I used, in which case, you will need to experiment to figure out the right amount to add.

- Give the mixture a quick stir with a fork or chopsticks to combine everything then attach the bowl to your stand mixer, attach the dough hook, and run on medium high speed for 10 minutes. It's a dry dough so it will look like a bunch of gravel at this point. Use your hands to divide it in two and press together into two balls. Wrap with plastic wrap and let the dough rest for at least 1 hour.

- Flatten each ball out on a flat surface, and run it through the largest setting of your pasta roller a few times, folding it in half each time. The dough will be ragged the first few runs though but will smooth out. When it starts rolling out smoother, fold it up into a square and wrap with plastic wrap and store it in the fridge overnight.
- When you're ready to cook it, prepare a large pot of water by salting it and bringing it to a boil. Each ball will make enough for 2 bowls of ramen, so figure out how much you need. Flour the dough generously and roll it out to the 3 setting on your pasta roller. Cut the dough in half so you have two sheets of dough a little over 1 foot long and flour generously again.
- Use the spagetti attachment to cut the pasta into long thin noodles, dusting them with flour as they are cut to keep them from sticking together.

- Boil the noodles until they are slightly firmer than the final consistency you want, since they will continue cooking after you remove them from the water. I usually let them boil for about one minute.






Marc Matsumoto says
Hi Dan, I checked both the bottle and the maker's website and it doesn't mention the concentration anywhere, so I'm afraid I can't give you an answer. You're probably going to have to experiment. Try preparing a few bowls of solution at different concentrations and use them to make a small bit of dough. You want enough kansui to turn the dough yellow, but not any more than necessary.
Dan says
Hi Marc, I'm finally feeling adventurous enough to try making my own ramen noodles and was wondering if you could answer a question Google is failing to: What's the conversion between liquid and powdered kansui? Thanks!
Kaori says
Love this recipe and use it a lot! Thanks Marc!
Aaron Freeman says
So, you use the same liquid amounts as you would with the powder? Good to know, because I ruined 3.5 c of dough using too much kansui liquid...
Dana Beckstoffer-Yares says
Thanks! I'll give that a try.
Marc Matsumoto says
Hi Dana, it depends on where you live, but Chinese grocery stores usually carry it in the same aisle as soy sauce and other bottled sauces.

Where can I buy the Kansui??
David says
Hi Marc. Thank you very much for sharing this recipe. I have been seeking this for a long time. I didn't get success( not firm enough) for the first time because I didn't follow your procedure. I got very OK noodle (80% similar to the outside ramen) for the second time. Now I realize "... mixer and run on medium high speed for 10 minutes" meaning something. It will distribute the kansui more even so that will help to bond the protein much better by the mixer strike. The result is the firm noodle.
I hope more people will get help/ benefit from your website.
Marc Matsumoto says
Hi Rei, sorry I missed your question. it’s best to make these noodles fresh as the color tends to turn an unappetizing shade of grey when they’re left in the fridge for too long. The broth can be made ahead and frozen.

Hello Marc! What would be the proper storage for this noodles and how long would they last refrigerated? Im planning to have a party on a weekend, but do the noodles ahead of time as I will be doing the broth from scratch as well. Thanks!
Habitablaba says
Although I doubt anyone will check this a year after the original post...
I've made successful gluten free & vegan noodles / pasta dough with just buckwheat flour and a 'flax egg' (3 tablespoons ground flax, 1/3c water, blend). I rolled it all out by hand with a rolling pin, so I'm not sure how it will stand up to a pasta roller. I also found that I had to be extra liberal with the flour on the rolling surface and pin, since the dough remained quite sticky.
Joe says
Thanks Marc!! I'm going to try it again!
Marc Matsumoto says
Hi Joe, you'll probably want to use more water if it's taking that long to come back to a boil, but the timing is based on when you put the noodles in the water.
Joe says
Hi Marc, when you say boil the noodle for just over a minute, do you mean from the time as soon as you put the noodles in the boiling water or after the water comes back to boiling again? Maybe I need to use more water but as soon as I put my noodles in, the water stops boiling and then takes about another minute for it to boil again.
Marc Matsumoto says
Hi Jared, if you primary objective is to give the noodles a green hue, I'd recommend using spinach powder. The green color from seaweed tends to give it a brownish green color that's not especially appetizing. That said, powdered konbu will give the noodles a great flavor. Good luck!
Jared Asachika says
Marc,
My primary goal was to see if the puree would give the noodle a slightly different texture and a green color. Overall, I wanted to make a green-noodled ramen topped with an assortment of seaweeds. I'll try the powdered dashi konbu though. Thanks!
Marc Matsumoto says
Hi Jared, I'm not sure what the purpose of adding seaweed, to the noodles would be, as most seaweed doest have a ton of flavor. If you're looking to infuse them with more flavor, you could add powdered dashi konbu to the dough. They do this in Hokkaido and it turns the noodles a mossy green and gives them quite a bit of flavor. It needs to be served in a really simple broth (like a clear shio) though otherwise the konbu gets lost. Kind of similar to how you would serve a flavored italian pasta really simply (olive oil and maybe a little cheese).
Jared Asachika says
Marc,
Just wanted to know... is there a way to incorporate seaweed puree into the ramen noodle recipe? I wonder if it would be similar to making spinach pasta. Or would the seaweed puree throw off the PH balance too much?
Marc Matsumoto says
Hi JimbreezyWho Dat Le, the gluten is what gives ramen its texture, without it they just won't be ramen. That said, there are lots of gluten-free pasta recipes out there if you're just looking to make noodles.
JimbreezyWho Dat Le says
I want to ask if there is a gluten free version of this recipe? thanks!

Hi Eating on Two Wheels. hand pulling noodles is a blast, but I think you'll be pretty disappointed if you try and pull this dough. It's far too dry and brittle to pull. That's probably why Japanese ramen noodles are almost always cut, not pulled.
Eating on Two Wheels says
Hand pulling is fun! You might not end up with perfect looking noodles, but they'll still taste great, and you'll have all sorts of laughs bouncing and stretching the rope! I had success hand pulling with a baking soda (not even baked soda) recipe, but didn't get the nice yellow color (or, I suspect, the really springiness). I'd like to try it again with the kansui or baked soda.
Jim Piriyalertsak says
I tried your recipe yesterday and it's turn to be quite OK. However I need to make noodle a bit tougher. Your one is soft and elastic. I have found that if you add some salt you might toughen the noodle. I will try again on Monday and I will add about 4.5 gram to the recipe. Any suggestion before I process would be nice.
ikoiko says
Thank you sooo much for the recipe! I've been looking for years for a handmade ramen noodle recipe. I went to our Thai Market to find the kansui but they didn't have any. I did see the lye water though but the owner said it wasn't for making noodles. I kind of think it's because he'd lose money from me making my own so he lied. 😛 I'm going to do the baked baking soda recipe and when I get to a bigger city I'll go and find the kansui. Thanks, again!!!! 😀
josh says
awesome... thanks.
I have been cooking for a living for 21 years... appreciate the hand-over of knowledge greatly!.
JF says
Thanks for that I made it with the Kitchen aid attachment to number 5, I will give my next batch a go to #4
Shih-An Cheng says
Thanks for the post. I read a book "Ivan Ramen" by Ivan Orkin, he uses the combination of rye flour/cake flour/bread flour which suppose to give it more flavor. (70g rye/ 620 g cake/ 300g bread/10 g kansui powder/430 ml water/13g salt) This book is quite fascinating, you might really enjoy it.
Marc Matsumoto says
Hi Isho, it doesn't really matter as long as the water is not boiling and is not cold. I'd say anywhere from 35-60 degrees C should be fine. Using warm water aids in the formation of gluten.
Isho says
What temperature is the "warm water"
Jason C Reasoner says
bonus points for the Harold McGee reference
Steve Ford says
I don't know about "Asian" flour, but when i lived in Japan they sold pretty much low protein (cake) or high protein (bread) flour, there was no all purpose.
Yaunchi says
It seems a lot of people are having problems finding or understanding the whole Konsui... To break it down simply Kansui is "Lye Water". It can be purchased on amazon or from several Internet stores. You also use this for making pretzels and other types of pastries. Note though.... The Lye Water has to be for cooking.... DON'T JUST GET LYE... You get sick or worse. There is an FDA requirement to be considered safe for human Consumption

Hi Marc, Thanks for the really insightful article and explaining the science behind this. I used the baked baking soda method with bread flour and it turned out great - uploaded a video of the process here as well: https://www.youtube.com/watch?v=1wySzXVxuUI
Keep up the good work with your site!

Hi Joe, I don't know Vegas very well, but any large Chinese grocery should carry it . If you happen to be in LA, try 99 Ranch Market.
Joe Sneed says
So where do I get Koon Chun Potassium Carbonate & Sodium Bi-Carbonate (kansui) ? I'm here in Vegas.
Matthew Amster-Burton says
FYI, I just tried this recipe using Harold McGee's baked baking soda substitute for kansui, and it worked great. I started with 1 teaspoon of baked soda, figuring I'd adjust as needed, but 1 teaspoon turned out to be fine.

Peek into your roller and estimate the thickness that is the same width as your spaghetti cutter. I have 8 settings as well with the kitchen aid stand mixer attachment, perhaps you use that. If so, I find setting 4 makes noodles with a symmetrical cross section
Luke LeClair says
Hi Mark, this may be a stupid question. My pasta machine only has 8 settings, so do I still use the 3rd last setting when rolling the dough out before I put it through the spaghetti cutter?
Amanda White says
on the dvd Kung Fu Panda in the special features there is a video with Alton Brown on ramen and the noodles. In case you wanted to know how one restaurant forms the noodles.

Ramen is awesome says
Hi Marc,
Thank you so much for this recipe. I had instant success. I still have a ways to go before I can be truly proud of my ramen, but on my second try I got good color and decent texture. I don't have a mixer or a pasta roller and did it all with a wooden spoon, bowl, a rolling pin and a knife. I am confident now that with some hard work and experimenting (and maybe eventually some better equipment) I will make ramen that the ramen gods will deem worthy. Thanks a million and when I am not super broke I will donate.
Marc Matsumoto says
Harold McGee has a technique for making alkaline noodles by baking baking soda in the oven. https://www.nytimes.com/2010/09/15/dining/15curious.html?ref=dining
I've never tried it though so I can't vouch for it.
Nay Jade says
i cant find kansui here.. its hard to find it everywhere can i make it by myself..? using something familiar in here? please help me, i want to make ramen for my husband >_<
i wacthed japan movie "chef from north polar" theyre mention about making ramen without kansui, they cant make ramen because theres no kansui, but the scientist part told the chef to make kansui with something i cant clear enough to know, baking powder or baking soda or something..
are there any other way to make it?

Flower & Monster says
Yes, too much gluten. Asian wheat doesn't have that much. It's a cross between cake and all-purpose flour.
Joe says
I just tried this recipe with King Arthur bread flour, and there is way too little water. I follow the weight measurements, so there is unlikely to be a problem with too much flour. The weather here is fairly humid as well. It could be the extra high protein content in King Arthur flour. I had to add almost another 2Tsp of water to get to dough to even be workable. My suggestion to others attempting this recipe is to add a teaspoon of water at a time half way into the mixing process to make sure there is not too many dry spots in the flour.
Marc Matsumoto says
Hi Leslie, the firm chewy texture of ramen noodles is produced by the gluten in wheat flour reacting with the kansui. It's going to be tough reproducing this with a gluten-free flour, though if I were going to take a stab at it I'd probably start by using a high ratio of tapioca or kudzu starch to a filler flour. You're also going to want to omit the kansui and add some turmeric for the yellow color.
Leslie says
Anyone experiment with Gluten Free flours when making noodles?
Mackenzie says
Looks good
