3.1 x 4.5 mm (0.122 x 0.177 in)
2.6 x 3.0 mm (0.102 x 0.118 in)

ii. Ingredients are different

Ramen noodles are made of kansui (an alkaline solution) and milled flour.
Udon noodles are made of water, salt, and milled flour.
Kansui makes noodles...

1. Yellow,
2. Chewy, and
3. Gives it its distinct ramen noodle flavor.


1. Because of kansui, the color of ramen and udon noodles are different...

Ramen noodles have a yellowish color.
Kansui and flour produce a yellow organic compound called chalcone when they are mixed together.
This is the cause of the yellowish color of ramen noodles.

Udon noodles are white in color because that is the original color of milled flour.

2. Because of kansui, the texture of ramen and udon noodles are different...

Ramen noodles are stretchy and have a chewy texture.
Kansui changes the structure of gluten and noodles, which is where it gets its distinct texture.  

Udon noodles are flexible, springy, bouncy, gummy and sticky.
Do you know how udon chefs give the noodles this texture?
The answer is...
Forming gluten structure.

The inside of a well-made udon noodle comprises a mesh-like structure made of gluten, and the structure covers starch.
In order to make this structure,
Chefs need to pick the best flour, while being careful of the water addition rate and the amount of salt.
They put a lot of effort into mixing, stepping on, and resting the dough.
Unlike ramen noodles, udon noodles need to be cooled down before serving.
Chefs put udon noodles in a cold water bath.
It doesn’t matter if these noodles will be served hot or cold.
You must wash your boiled noodles in cold water.
After cooling down the udon noodles, chefs pour hot soup on top of udon to serve hot udon.
Do you know the reason why chefs cool the udon noodles down?

There are two reasons.
Reason Number 1: You can prevent the udon noodles from getting soggy.
If you don't cool the noodles down completely, the noodles will become over cooked.
That means udon noodles lose their springiness and bounciness.
Reason Number 2: You can get rid of the stickiness of udon noodles.
Udon noodles tend to have a sticky surface because of starch.
Starch comes out of noodles while you are boiling it.
If it is too sticky, the noodles will get stuck to each other.
That is why you wash udon noodles in cold water.

3. Because of kansui, the flavor of ramen and udon noodles are different...

Do you know the reason why ramen has a distinct flavor?
The answer is...
When you mix kansui and flour, a little tiny bit of ammonia is created.
Actually, it is the flavor of ramen noodles.
A lot of ammonia smells really bad, but a low concentration of ammonia is what gives ramen its distinct good smell.
(The amount of ammonia is very little so it won't have any adverse impact on your body)
Udon noodles don't require any kansui to make, so udon noodles smell of flour.

iii. Ramen noodles are wavy or straight and udon noodles are always straight.

1. Ramen noodles are straight or wavy

Straight noodles are commonly used for thin noodles like Kyushu-style tonkotsu ramen.
Curvy noodles are commonly used for thick noodles.
For thick noodles, in order to create an optimal surface area to volume ratio,
Chefs make the noodles wavy so that it can hold and keep more soup on the surface of the noodles.

2. Udon noodles are straight

Quickly slurping straight udon noodles gives a nice mouthfeel.
It is very addicting.

3. Shapes of cross-sections are important too

Did you know?
There are square cross-sections and rectangular cross-sections too.
Ramen noodles have various cross-sections and udon noodles always have short rectangular cross-sections. 
Square: Tend to absorb more soup
Rectangular: Goes well with simple soup taste, like shio or shoyu ramen
Rectangular (vertical): Noodles in this formation absorbs the most soup
Rectangular (horizontal): Used for flat noodles as they have a smooth surface
Circular: They have a smooth texture. Used for noodles like somen or spaghetti

Ramen broth is made up of water and a combination of pork bone, beef bone, chicken, bonito, dried sardines, konbu (kelp), mushroom, or scallops.
Ramen soup has 4 primary types. Shoyu ramen, miso ramen, tonkotsu ramen and shio ramen.
Take a look...

1. Shoyu Ramen:

Shoyu ramen consists of broth, sauce, flavored oil, noodles, and toppings. 

The sauce is made up of mainly soy sauce and some other ingredients. 
This is how this ramen got its name (shoyu means soy sauce in Japanese).
Shoyu ramen is a light soup broth, which is a nostalgic and familiar taste for Japanese people.
Because of this, shoyu is the prototype for the different types of ramen in Japan.
It is usually made from chicken or pork broth. 
Sometimes, this soup stock, made up of various vegetables, konbu (kelp), or niboshi (dried sardines), is added to the broth to give depth to the flavour of the soup.

Because pork bones are boiled for long hours in high heat and components of the bone is melted into the soup,
The resulting soup of tonkotsu ramen is very rich, thick, and cloudy.
This soup contains a lot of umami. This is due to the inosinic acid from the bones.
And fat and gelatin from the bones give the broth its distinctive taste.
Noodles of tonkotsu ramen are usually very thin.
Toppings of this ramen are quite simple - usually, green onion, chashu sesame, ginger, garlic, and karashi takana are used as a pairing to this type of ramen.

But in order to keep the broth transparent, you can't boil these bones at high heat.

ii. 2 Basic types of udon broth

Udon has 2 primary types. Kanto-style udon and Kansai-style udon.
They are names of regions. Kanto region is in the east part of Japan and the capital of Japan, Tokyo, is located there.
And Kansai region is in the west part of Japan and Osaka and Kyoto are located there. 

1. Soup of Kanto-style udon soup is saltier and has a brown color. 

The reason why Kanto-style is saltier is you use dark soy sauce when you make this region’s udon soup.
Kelp and bonito are used for this soup stock, but the taste of bonito is very distinctive for Kanto-style soup. 
In the Kanto region, people call this soup "tare"(たれ).
Tare means sauce in Japanese.

2. The soup of Kansai-style udon is less salty and has a light yellow color. 


It is said that Kansai-style udon soup is thin. People there want to taste the soup stock more than the soy sauce.
You use light soy sauce in order to make Kansai-style soup.
Soy sauce for Kansai-style is for only adding a little bit of flavor.
And since you only use a little bit of soy sauce, the soup is transparent.
Bonito, dried sardines, and kelp are used for its soup stock.
In the Kansai region, people call this soup "dashi"(だし).
Dashi means soup stock in Japanese.
Kanto and Kansai have different feelings about udon,
So that the language used to describe the soup of the udon is different. 



4. Do ramen and udon both use flavored oil?

Ramen uses flavored oil called koumiyu, but udon doesn't use flavored oil.
Do you know why flavored oil is in ramen?
The answer is...
Seasoning oil gives ramen its flavor.
In addition, using koumiyu keeps the ramen hot because it covers the surface of the soup, trapping the heat inside.
Some types of koumiyu include chicken oil, pork fatback, and bonito oil.

13. Can I use udon noodles for ramen?

I have never heard of it but you can do it.
There is no law that prohibits using udon noodles with ramen soup, but no restaurant does it.
Probably I should review this ramen udon later…

There is udon ramen in Tottori Prefecture.
It is called “suramen”.
This is a dish that you use ramen noodles in udon soup.
Except for the ramen noodles, it is actually an udon dish.
Soup is udon soup, toppings are for udon: kamaboko, bits of deep-fried tempura batter, and green onions.
Actually it is not popular at all.
There are only a few restaurants that serve this suramen.

14. Are there different manners for eating ramen and udon? 

No, there is no difference between ramen and udon in terms of manners.

i. But the sound of slurping is different.

When you slurp ramen, it sounds like…
Zuuuuu zuuuu…..(loud)
When you slurp udon, it sounds like…
Zozo zozo…..(Quiet)
When people eat udon, they tend to eat less noisily.
The culture of slurping noodles came from eastern Japan.
Since udon was developed in western Japan, you don’t slurp udon as much as ramen.

ii. Why do the Japanese slurp noodles? 

1. You can prevent noodles from getting soggy and soup from getting cold. 

If you slurp, you can eat noodles quickly, so you can enjoy its chewiness.
In addition, it is rude to the chef to not eat food as soon as it is served to you.

2. You can enjoy the flavour of noodles more

You can enjoy the flavor of ramen at least 4 times more if you slurp.
Having a combination of air, noodles and soup together allows you to feel more flavor in your mouth.

3. You don't want to bite off excess noodles

Japanese people find it disgusting to bite off excess noodles and for the excess pieces to go back into the soup bowl.
That is why slurping is preferred because you can bring all the noodles into your mouth at once.

What about frozen udon noodles?

You can use a microwave too.
Usually it takes 3 minutes to cook in a microwave(600W).
This is the reason why frozen udon is more common for people.

16. How to make ramen noodles

So, are you interested in making your own noodles at home by now?
Sounds difficult and impossible?
No, it is actually very SIMPLE!
Here's my go-to (egg-free) recipe:

Ingredients (for 6 bowls):
Wheat Flour 500g
Baking Soda 5g
Water 220cc
Salt 5g
Potato Starch* - As you see fit
Rolling Pin
Cutting Board
Measuring Cup
Measuring Spoon
1. Mix baking soda, salt, and water together
2. Mix flour with 80% of the liquid mixture you made in the previous step. Leave some of it for use later.
3. Wrap dough with a plastic wrap for 5 minutes
4. If the dough looks a little too dry, add the liquid from "step 1" little by little until it is the right consistency
5. Put the dough into a large plastic bag and step on it to make it flat.
6. Fold the dough and put it back in the plastic bag and continue stepping on it until it gets flat again. Repeat this step 3 times.
7. Roll the dough into a ball-shape and cover it up with a plastic wrap
8. Let it sit for one hour
9. Divide the dough ball into 6 equal portions. Using a rolling pin, flatten out each of the portions separately.
It may be a little hard at the beginning to roll it out. But as the dough becomes flatter, it becomes easier to roll it out.
10. Fold the sheet of dough into itself until it is 10cm in width. Be careful when folding, do not press too hard or the dough may stick together.
11. Cut the folded sheet of dough using a knife
TIP: Try to push your knife from the top against the sheet. Do not slide your knife.
12. Once cut, loosen the noodles a bit. If you want to make the noodles wavy, knead the noodles lightly.
The potato starch in the recipe is to be powdered onto a wooden board before you start rolling out the dough.
 This powdery substance prevents noodles from sticking together.  

17. How to make udon noodles

Ingredients (for 6 bowls):
Wheat Flour 600g

Salt 30g

About the Author


Kei is a self-proclaimed ramen lover, blog writer and founder of "Apex S.K. Japanese tableware".

"I am from Ibaraki, Japan.

Ramen is great! It can bring you a sense of happiness and satisfaction that no other food can. I have been eating ramen for 30 years.

If there is no ramen, my life would be miserable.

Ten years ago, I worked as an office worker. The job was really stressful - excessive working hours, low wages, unpaid overtime work, and constantly being yelled at by my boss.

I was new and alone, no girlfriend, no friends, and felt very lonely.

My only oasis was the ramen shop near the office. For me, the ramen chef there was literally an angel. I saw a halo on his head. (No joke)

Tonkotsu shoyu ramen was my all-time favorite. He made ramen with broth chock-full of umami flavor, nice chewy handmade noodles, and tender chashu.

My greatest dream is connect people with ramen through my blog. I want to share a lot of interesting and funny stories and ramen trivia with you.

Knowing more about ramen can help you appreciate your ramen and make it taste extra delicious."

    Hello Robert-san. Thank you for reading my blog and leaving a comment! That sounds wonderful. Fusion dishes are so innovative and it is always so fun to experiment with cuisines from different cultures. We would love to see your creation when you make it!

    Kon ban wa Kei san ? Watashi wa Robert san from Czech Republic, Prague. Your blog reads like a wonderful religion about JOY. Very nice. You should know that our czech middle age (1400) cuisine was just made mostly from soups – soups that today almost nobody can cook anymore in czech republic. I had japanese friends from Kyoto – they used to study art with me in Munich and Düsseldorf. But I want to try to mix Ramen / Udon with czech style soups – like (Zelnacka, Gabbage soup with mushrooms and eggs) or Bramboracka – or another hundred different.
