Walking Into Chef Masa's Kitchen Is Like Stepping Into Summer
Walking into Chef Masa's kitchen is like stepping into a quieter season of cooking. The burners that normally roar through service sit still. The air carries the fragrance of toasted sesame and freshly grated ginger instead of long-simmered broths. On the counter, bundles of soba noodles wait beside bowls of chilled dipping sauce, their simplicity almost deceptive.
Summer recipes often reveal a chef's discipline more clearly than elaborate dishes. There is nowhere to hide. Every ingredient is exposed. Every flavor must justify its place. This is precisely why Chef Masa enjoys developing cold noodle dishes. The elegance lies in precision, timing, and respect for ingredients that require very little intervention.
Among the team's favorites is this Cold Soba With Sesame-Tahini Mentsuyu, a dish that transforms pantry staples into something deeply satisfying. It is cooling, nourishing, and surprisingly complex despite requiring almost no cooking beyond preparing the noodles themselves.
The Origin

The story of this dish begins during one particularly humid Singapore afternoon. Service preparations were underway, and several members of the team found themselves searching for something refreshing that could still provide enough substance to carry them through the evening.
Chef Masa had been contemplating the balance between traditional Japanese mentsuyu and richer sesame-based sauces often found in regional cold noodle dishes. Tahini, commonly associated with Middle Eastern cooking, offered a familiar nuttiness that mirrored Japanese sesame paste while contributing a silkier texture.
Each iteration was a quiet revelation. Some versions became too heavy. Others lost the delicate umami foundation that makes mentsuyu so comforting. Eventually, Chef Masa found harmony through restraint. The tahini supported the dashi rather than overpowering it.
The resulting bowl reflects a philosophy often seen throughout his kitchen. Innovation works best when it deepens tradition rather than replacing it.
Flavor Philosophy and Techniques

At the heart of this recipe is contrast and harmony.
Cold soba offers an earthy, almost mineral quality. The sesame-tahini mentsuyu introduces richness without weight. Fresh cucumber contributes crispness, while scallions add brightness and lift.
Chef Masa employs subtlety throughout the dish. The tahini is not intended to dominate. Instead, it softens the edges of the mentsuyu, creating a sauce that feels creamy while remaining remarkably light.
This juxtaposition of textures creates the dish's appeal:
- Chewy soba noodles
- Silky sesame dipping sauce
- Crisp vegetables
- Fresh aromatic garnishes
Plating, color, and aroma are not afterthoughts. They are part of the storytelling. The pale sauce, dark noodles, vibrant green vegetables, and scattered sesame seeds create a bowl that feels calm before the first bite is even taken.
The Recipe

For the Soba
- 250g dried soba noodles
- Ice water for chilling
For the Sesame-Tahini Mentsuyu
- 4 tbsp mentsuyu concentrate
- 3 tbsp tahini
- 250ml cold water
- 1 tbsp soy sauce
- 1 tsp sesame oil
- 1 tsp grated ginger
For Garnish
- 1 cucumber, julienned
- 2 scallions, thinly sliced
- 1 tbsp toasted sesame seeds
- Optional nori strips
Step-by-Step Guide
1. Cook the Soba
Bring a large pot of water to a boil and cook the soba according to package instructions.
Drain immediately and rinse under cold running water until completely chilled.
Kenji's Note: This step removes excess starch and gives the noodles their characteristic clean texture.
2. Prepare the Sesame-Tahini Mentsuyu
Whisk together:
Mentsuyu
- Tahini
- Cold water
- Soy sauce
- Sesame oil
- Grated ginger
- Continue whisking until smooth and silky.
Chef's Insight: The cold water should be added gradually. This helps the tahini emulsify properly and prevents lumps from forming.
3. Prepare Garnishes
Julienne the cucumber and slice the scallions.
Toast sesame seeds briefly if they are not already toasted.
4. Assemble
Arrange chilled soba in serving bowls.
Serve the sesame-tahini mentsuyu alongside or drizzle lightly over the noodles.
Top with cucumber, scallions, sesame seeds, and nori.
5. Serve Immediately
Cold noodle dishes are at their best when served immediately after assembly.
Chef's Tip: Place serving bowls in the refrigerator for 15 minutes beforehand for an even more refreshing experience.
Tasting Notes

The first forkful of this dish is a revelation.
The aroma arrives first. Toasted sesame rises gently from the sauce while ginger contributes a subtle freshness. The soba itself carries a pleasant earthiness that immediately grounds the dish.
Texture follows next. The noodles remain pleasantly firm while the sauce coats them with remarkable smoothness. Crisp cucumber introduces contrast, ensuring each bite remains lively.
As the flavors mingle, the depth of the mentsuyu begins to emerge. Umami from dashi and soy sauce forms the foundation. The tahini adds richness without heaviness, while ginger quietly brightens the finish.
What makes Cold Soba With Sesame-Tahini Mentsuyu extraordinary is not just its flavors but its multi-sensory experience. It cools the body while remaining deeply satisfying, proving that simplicity can possess remarkable depth.

Behind the Scenes: Chef Masa’s Insights

Chef Masa often says, "A great summer dish should refresh the body while still feeding the spirit."
In our kitchen, cold noodle dishes receive the same level of attention as far more elaborate creations. The sauce is tasted repeatedly. Garnishes are adjusted carefully. Even the temperature of the serving bowl is considered.
The dish is also a lesson in restraint. There are countless ingredients that could be added, yet very few that truly need to be. Every component has a purpose. Every flavor supports another.
The elegance lies in precision, timing, and respect for ingredients. When those elements come together, even a simple bowl of soba can tell a remarkable story.
