Healthy Japanese Glass Noodle Salad (Harusame Sunomono)

[Ban San Si] Silky & Refreshing: The Ultimate Harusame Sunomono (Glass Noodle Salad)

Harusame Sunomono (Vinegared Glass Noodle Salad) is a beloved staple in Japanese home cooking. It’s light, refreshing, and naturally low-calorie and gluten-free, making it a perfect side dish for any healthy meal.

But did you know its traditional name is Ban San Si (伴三絲)? The Kanji characters tell the story of this dish:

Ban (伴): To mix or toss thoroughly.
San (三): Three key ingredients.
Si (絲): Delicate, thread-like shreds.

True to its name, this vibrant salad features at least three colorful ingredients sliced into fine strips and tossed with silky glass noodles.

As a nutritionist, I love this recipe not just for its texture, but for how easily it adds fiber and nutrients to your plate. Today, I’ll share my go-to recipe along with professional tips to help you achieve that perfect, tangy balance!

🥗 Ingredient Spotlight

For this recipe, I used a vibrant trio of egg, cucumber, and kanikama (crab sticks), but feel free to get creative!

Classic Additions: Carrots, ham, or wood ear mushrooms (kikurage).
Fun Fact – Kanikama: While it looks and tastes like real crab, it’s actually a type of kamaboko (fish cake) primarily made from Alaska Pollock. It’s the perfect budget-friendly partner for glass noodles!

💡 3 Pro-Tips for Success

1. Fry Your Eggs in Sesame Oil

When making your thin egg crepes (usuyaki tamago), use sesame oil instead of neutral oil.

Aroma: The nutty fragrance adds a beautiful accent to the overall dish.
Non-stick Texture: The oil coating on the eggs actually helps prevent the glass noodles from clumping together once mixed.

2. Check the Boiling Time for Your Noodle Type

The texture of Harusame (glass noodles) varies significantly depending on the starch used. Always check the package and ensure there is no hard “core” left in the center.

Type	Characteristics
Mung Bean(Ryokuto) Harusame	Made from mung beans or peas. Firm, elastic, and heat-resistant (doesn’t break apart easily).
Potato/Sweet Potato Harusame	Made from root vegetable starches. Soft and chewy texture; absorbs flavors exceptionally well.
Maroni	A specific brand made from liquefied potato starch, processed into flat, thin sticks. Famous for its silky-smooth slurp!

3. Elevate the Finish with Light Soy Sauce & Black Vinegar

Usukuchi (Light) Soy Sauce: Using a lighter-colored soy sauce preserves the vibrant colors of the vegetables and eggs, resulting in a more beautiful presentation.
Vinegar Choice: While grain or rice vinegar is standard, I recommend Black Vinegar for a deeper, more mellow complexity.

📋 Ingredients (Serves 6) : Harusame Sunomono

Note: Dried glass noodles expand to about 4 times their weight when boiled.

Dried Glass Noodles (Harusame Vermicelli): 80g
Cucumber: 80g (julienned/thinly sliced)
Imitation Crab (Kanikama): 30g
Egg: 1
Sesame Oil: 4g (for frying the egg)
White Sesame Seeds: 5g

【Dressing】

Vinegar of choice: 48g (grain, rice, or black vinegar)
Sugar: 16g
Light Soy Sauce (Usukuchi): 16g
Karashi (Japanese mustard): to taste

🍳 Instructions : Harusame Sunomono

Make the Omelet Strips
- Beat the egg well in a bowl. Heat sesame oil in a pan, pour in the egg to create a thin sheet, and cook. Once cooled, slice into thin strips (kinshi tamago).
Prep the Ingredients
- Slice the cucumber diagonally into 3mm pieces, then slice again into thin strips. Cut the imitation crab into 3cm lengths and shred by hand.
Mix the Dressing
- In a large bowl, combine the vinegar, sugar, light soy sauce and karashi. Stir lightly.
Boil the Noodles
- Boil the glass noodles in boiling water for about 4 minutes (or according to the package instructions). Drain in a colander.
Infuse the Flavor (Pro-Tip!)
- Immediately toss the piping hot noodles into the bowl with the dressing. The heat melts the sugar and allows the noodles to absorb the flavor deep into their core.
Finish
- Once the noodles have cooled slightly, add the egg strips, cucumber, imitation crab, and sesame seeds. Toss everything together, and you’re done!
