(2) Ryota's One-Point Advice: The Science of "Koshi" and Gluten Network
Hi everyone, it's Ryota here! Have you ever wondered why Italian pasta and Japanese Udon have completely different textures, even though they are basically made of the exact same things: just wheat flour, water, and salt?
Scientifically speaking, the secret lies in how we build the "gluten network."
Pasta is made from hard Durum wheat and is forcefully extruded through machine holes in a single direction. This creates a dense, tight texture with a hard core, known as "al dente." On the other hand, Japanese Udon takes a completely different approach by using foot-stepping. By stepping on the dough from various angles, we interweave the protein strands in all directions, creating a strong, three-dimensional "gluten jungle gym!" This structure is what gives Udon its signature "Koshi"—that beautiful, chewy bounce that pushes back when you bite into it!
To achieve the ultimate Udon texture, two more scientific steps are crucial:
- Salt and Jukusei (Resting): While pasta makers put salt into the boiling water, Udon makers put salt directly into the dough to tighten the wheat proteins. Letting the dough sleep (Jukusei) allows water molecules to distribute evenly at a molecular level, giving it incredible smoothness and elasticity.
- Cold Wash (The Tightening Magic): Shocking the freshly boiled Udon in ice-cold water instantly tightens the heat-expanded surface. It works just like a skincare routine for your noodles, washing away excess slimy starch to complete a perfect contrast: a silky-smooth outside with a deeply chewy inside.

(3) Ingredients (Serves 2)
For the Udon Dough:
- All-purpose flour: 300g (or a 1:1 mix of bread flour and cake flour)
- Water: 140ml - 150ml (adjust slightly depending on your room's humidity)
- Salt: 15g (about 3 tsp)
For the Delicious Kake-tsuyu (Udon Soup):
- Dashi Stock: 600ml (Don't know how to make authentic Dashi? Check our [Basic Dashi Guide])
- Soy sauce: 3 tbsp
- Mirin: 3 tbsp
- Salt: 1/2 tsp
(4) Instructions
- Dissolve Salt: Dissolve the salt completely in the water. Pour this salt water into the flour little by little, mixing gently with your fingertips in a circular motion until it forms a crumbly texture like breadcrumbs. Gather it into a single dough ball.
- Foot-Stepping (Jungle Gym Magic): Place the dough inside a thick plastic Ziploc bag. Lay a towel on the floor, place the bag on top, and step on it evenly with your feet until it flattens. Fold the dough inside the bag and step on it again. Repeat this process 3-4 times to build that strong gluten jungle gym!
- Jukusei (Resting Phase): Shape the dough into a smooth ball, wrap it tightly in plastic wrap, and let it rest at room temperature for 30 to 60 minutes. This allows water to spread beautifully at a molecular level.
- Roll and Cut (Katana Method): Dust your work surface with flour. Use a rolling pin to flatten the dough into a 3mm-thick rectangle. Fold the dough like an accordion (zigzag layers), and cut it into 3mm-wide noodles using a sharp knife.
- Boil: Bring a large pot of water to a rolling boil. Gently separate the noodles and drop them into the water. Cook for 10 to 12 minutes until they reach your preferred chewiness.
- Cold Wash (The Tightening Magic): Immediately transfer the boiled noodles into a bowl of ice-cold water. Wash them gently with your hands to remove the slimy surface starch and drain thoroughly. Even if you want to eat warm Udon, doing this cold wash first is the secret professional trick!
