Mike was a twelve-year-old boy from America who had recently developed a deep fascination with Japanese society. He enjoyed watching Japanese documentaries and travel shows, especially those featuring everyday life, local communities, and unique cultural traditions.
His mother, Kelly, who prided herself on being well-informed, often discussed news and social topics with him, though she admitted Japan’s social structure was more complex than she expected.
His father, John, was a busy corporate worker who had traveled to Japan many times but rarely experienced life outside business districts in big cities.
They also knew Nobu, a Japanese college exchange student who often visited their home and shared stories about school life, customs, and regional differences.
Mike liked Japan, and he realized there was still so much more to learn about the country’s diverse and evolving society.
Prologue
Most wheat-based foods are made by adding water to flour. Good examples are bread and pizza dough. While eggs are sometimes used, water is generally the essential ingredient.
The amount of water used in these foods varies on a case-by-case basis. In Japanese cuisine, consider “Okonomiyaki” and “Monjayaki“. Okonomiyaki has a thick, creamy batter, but Monjayaki uses even more water, making it much runnier. (By the way, I plan to introduce these two dishes in a separate article) . These examples show just how vital “water content” is to wheat-based foods.
So, does the water content in Ramen noodles vary as well? And if so, what kind of characteristics emerge from those differences? Let’s take a closer look at the water content of Ramen noodles.
Act1:Mike Learns About Wheat and Water
One day, Mike decided to make pancakes while visiting a friend’s house. However, Mike didn’t have much cooking experience and struggled quite a bit.
Pancakes are made by mixing water into a flour base and heating it, but Mike noticed that the final state of the pancake changed depending on the amount of water he added. This got him thinking: “What about other wheat-based foods?”. How far will Mike’s curiosity take him?
Mike: “I’m home!”
Kelly: “Oh, you’re late. Weren’t you busy making and eating pancakes at your friend’s?”
Mike: “Yeah, I was. But…”
Kelly: “But?”
Mike: “I was a bit clumsy and it took a lot of time. That’s why I’m late.”
Kelly: “I see. Just make sure to let me know next time.”
Mike: “I will. Anyway, pancakes are made by mixing water with flour, right?”
Kelly: “That’s right. Technically, you mix several things into the flour, with water being the final step before cooking.”
Mike: “I realized that the amount of water added at that stage changes how they turn out.”
Kelly: “Of course. If you use more water, the pancakes become more moist, don’t they?”
Mike: “What about bread dough?”
Kelly: “I’ve heard that requires very delicate adjustments. It’s difficult because things like the weather can affect it.”
Mike: “So water content really is important. Humidity must affect it too.”
Kelly: “That’s likely true.”
Mike: “It made me think—Ramen noodles are also made from wheat, right? I wonder if the texture changes depending on the amount of water?”
Kelly: “That’s a good point…”
Act2:Kelly Explains Noodle Making
Mike: “Mom, you were always great at making pasta. Is there a hint in how you do that?”
Kelly: “Well, for pasta, you knead flour with eggs, salt, and water… Now that you mention it, changing the proportions of those ingredients does change the texture.”
Mike: “I knew it! The water content is a key factor in the taste.”
Kelly: “Thinking about it now, you’re absolutely right.”
Mike: “So, what about Ramen noodles?”
Act3:Nobu Introduces the Water in Noodles
Nobu: “Hello!”
Kelly: “Oh, hi Nobu.”
Mike: “Hey! Listen, I have something I want to ask you right away.”
Nobu: “What is it? Tell me.”
Mike: “Ramen noodles are made with flour, water, and
Kansui (alkaline water), right?”
Nobu: “Yes, flour, kansui, and water are the basic ingredients.”
Mike: “I was wondering, does the taste change based on the ratio of those ingredients?”
Nobu: “Oho! You’ve noticed something very important.”
Mike: “So, does it?”
Nobu: “To put it simply, the noodles feel different depending on the amount of water.”
Kelly: “How exactly do they differ?”
Nobu: “First, let’s look at the terminology. The ratio of water mixed in relative to the amount of flour is called the ‘Hydration Rate’ (Kasuiritzu). If a lot of water is used, it’s a ‘High Hydration Rate.’ If it’s a small amount, it’s a ‘Low Hydration Rate’. We call the resulting noodles ‘High-Hydration Noodles’ (Ta-kasui-men) or ‘Low-Hydration Noodles’ (Te-kasui-men)’.”
Nobu: “As for the difference, low-hydration noodles are firm and have a good ‘bite’. High-hydration noodles tend to have a chewy, ‘mochi-mochi’ texture.”
Mike: “Kind of like the pancakes!”
Nobu: “Exactly. But for Ramen, that’s not all. It affects other things too.”
Kelly: “What else does it affect?”
Nobu: “Actually, it changes how the noodles interact with the soup.”
Mike: “How they interact with the soup???”
Nobu: “Yes. Low-hydration noodles have less water to begin with, so they absorb the soup more easily. Also, because they have a higher proportion of wheat, you might notice a stronger wheat flavor.”
Kelly: “I see.”
Nobu: “There’s more. Because they absorb moisture easily, they tend to get soft (or ‘stretch’) faster.”
Mike: “So you have to eat them quickly, or they won’t taste good?”
Nobu: “Everyone has their own preference, but eating them quickly is probably best.”
Mike: “Makes sense.”
Nobu: “Now, let’s talk about High-Hydration Noodles. Since they have more water, they have the opposite characteristics of low-hydration noodles. First, they don’t absorb the soup as much.”
Nobu: “And the texture is very chewy and bouncy.”
Kelly: “I see. That sounds similar to pasta.”
Act4:Nobu Discusses Soup Compatibility
Nobu: “So, the major difference is how they ‘absorb the soup.’ Can you imagine how that works in practice?”
Mike: “No, I’m not sure.”
Nobu: “It’s a bit tricky. Because high-hydration noodles don’t absorb soup easily, it’s harder for thin soups to cling to them. Therefore, they actually pair very well with thick, viscous soups.”
Mike: “Wow, it’s all about the compatibility with the soup.”
Nobu: “Exactly. Think about the different types of Ramen soup.”
Kelly: “If we categorize them broadly, there’s Soy Sauce (Shoyu), Salt (Shio), Miso… and many others.”
Nobu: “Right. And even within Soy Sauce, the flavor and aroma vary depending on the variety. It’s incredibly diverse.”
Mike: “So, the amount of water in the noodles is one of the conditions that determines the final taste of the Ramen…?”
Nobu: “That’s it.”
Kelly: “Wait, doesn’t the water in the noodles change with the weather? Humidity must increase it.”
Nobu: “That may be true. But that’s where professional skill comes in. They can adjust for those changes.”
Kelly: “Impressive. I could never do that.”
Nobu: “Well, now that we understand it better, why don’t we go to a delicious Ramen shop again?”
Kelly: “Sounds like a plan!”
About the Hydration Rate of Noodles
To be honest, I didn’t know much about the hydration rate of noodles either. However, when I considered how moisture affects wheat, I had a hunch and looked into it. It turns out that water content significantly impacts the taste of Ramen.
I was also surprised to learn that it changes how the noodles interact with the soup. It made me realize once again just how deep the world of Ramen is. I truly take my hat off to the people of the past who built this culture.
Conclusion
After exploring the amount of water used in food, many of you might find yourselves more interested in Japanese Ramen culture. The fact that the state of the noodles is keyed to the water content and then paired with a specific soup variation is truly amazing.
There may be even more secrets hidden within Ramen. I look forward to exploring them, but let’s save those stories for another article. Please look forward to it!
