How MEN-EIJI Keeps Its Broth Identical Across Two Sapporo Venues

When a diner walks into MEN-EIJI Hiragishi BASE on a freezing Sapporo evening and orders a bowl of gyokai-tonkotsu, then catches a train to Duck Ramen EIJI the next afternoon for the same dish, they expect a sensory match. That expectation is the quiet contract between the kitchen and the customer, and it is the central obsession of founder Jun Furukawa. Australian travellers who treat ramen as seriously as a Melbourne barista treats a flat white understand this pursuit of repeatable excellence, because it mirrors the same logic that drives the country's specialty coffee wave: every variable has to be locked down, from grind size to extraction time, or the result drifts.

Gyokai-tonkotsu is a demanding medium. It blends pork bones with seafood, often including niboshi dried sardines, katsuobushi shavings and aromatic shiitake, then simmers the mixture for many hours until the liquid turns a creamy, opaque ivory. The broth carries layered umami, a faint oceanic salinity and the fatty sweetness that comes from properly rendered collagen. A single misstep, a handful of extra bonito flakes or a degree of extra heat, can tip the balance from silky to muddy. The brand's commitment to keeping that balance identical between its two venues is what separates a memorable bowl from a forgettable one.

Furukawa, who earned the brand a Michelin Bib Gourmand recognition and ran international pop-ups from Sydney to Singapore before settling back in Hokkaido, treats broth consistency as a craft discipline. He has spoken about how, early in his career, he watched a mentor in Osaka refuse to let a new apprentice taste the master stock for three months, insisting they learn the colour and aroma first. That philosophy of slow mastery shapes everything the kitchens do today, from how the bones are washed at dawn to how the final seasoning is tasted by the soup master before service.

This piece walks through the systems, rituals and people that keep the broth tasting the same whether a bowl is poured in the Hiragishi district or in the newer Duck Ramen EIJI space. It is the kind of behind-the-counter detail that food-obsessed travellers from Brisbane, Perth and beyond often seek out before booking a flight, because the answer lies in process rather than mystery.

A Shared Recipe Written in Grams, Not Spoons

At the heart of the operation sits a single recipe document. It is not a rough guide passed between chefs; it is a controlled file that lists every component of the gyokai-tonkotsu base down to the gram. Pork femur bones, pork back bones, chicken feet, dried scallop, katsuobushi, niboshi, kombu, shiitake stems, fresh ginger, whole garlic cloves and a measured splash of sake appear in fixed ratios that have been refined over years of service. Each chef in both kitchens refers to the same master sheet, updated only when Furukawa signs off on a change after a side-by-side tasting session.

The shift away from cup measures and pinches matters. Volume varies with humidity, packing density and the cook's mood, while mass does not. A Sydney ramen obsessive who watched a Tokyo chef weigh bonito flakes for a tsukidashi appetiser understood the principle instantly, and the same obsession applies here. Mass measurement is the universal translator between the two Sapporo kitchens, allowing the broth to taste identical regardless of who is stirring the pot that morning.

Sourcing Bones and Seafood With Surgical Precision

Consistency cannot exist without consistent inputs. MEN-EIJI works with a short list of long-term suppliers who deliver pork bones from a single regional abattoir and seafood that meets fixed specifications. The niboshi must come from a specific season's catch off Hokkaido's northern coast, with a moisture content below a set threshold. Katsuobushi is graded for thickness and smoke time, and the kombu is selected from a single cooperative in Rishiri so its glutamic acid profile behaves the same way every batch.

This level of supplier discipline echoes the way craft breweries in Adelaide source their hops, or how the top gelato makers in Fitzroy chase a single Sicilian pistachio farm. The kitchen rejects anything that drifts from the benchmark, even if the price looks tempting. A cheaper bag of niboshi might save yen, but it could push the broth's salinity off course and require a corrective seasoning that breaks the recipe, so the procurement team guards the supplier list like a sommelier guards a cellar.

Water Quality and the Mineral Profile Few Guests Consider

Sapporo's municipal water is famously soft, drawn from underground sources in the surrounding mountains, and that softness is itself an ingredient. Hard water loaded with calcium and magnesium can mute seafood aromatics and leave a chalky finish on the tongue, while soft water lets the glutamates in kombu and the inosinates in katsuobushi sing. Both MEN-EIJI kitchens draw from the same supply grid, which removes a variable many chain kitchens overlook entirely.

The team still goes further. Each venue runs its water through a charcoal and sediment filter, then tests the result monthly with a simple TDS meter. If a filter cartridge ages past its window, the broth can pick up faint metallic notes that throw off the delicate seafood top notes. Replacing the cartridges on a strict schedule, regardless of how the water looks, is a quiet habit that most guests will never see yet everyone in the kitchen guards fiercely. For a chef who trained in a coastal city like Sydney, where water hardness shifts from suburb to suburb, the idea of treating water as a controlled ingredient feels familiar. Australians who obsess over single-origin filter coffee already understand the principle: the same bean can taste wildly different depending on the mineral content of the water it meets, and broth behaves the same way.

Mirrored Equipment and Calibrated Heat

Pots, strainers, burners and thermometers are often the silent saboteurs of consistency. A pot with a thicker base holds heat differently from one with a thin aluminium shell, which means a recipe that targets a steady simmer can drift by several degrees without anyone noticing until the broth is tasted. MEN-EIJI standardises its equipment across both locations, using the same brand of heavy stainless stockpot, the same induction burners set to identical wattages and the same stainless mesh strainers for clarifying.

Calibration happens on a fixed rota. Every Monday morning, the kitchen supervisor at each venue checks probe accuracy against a calibrated reference thermometer and logs the reading. Drift of even half a degree triggers a replacement. The discipline feels almost clinical, and it is the kind of detail that reminds seasoned travellers of how the best kitchens in this part of the world operate, whether they are serving ramen in Sapporo or a tasting menu in a Melbourne laneway. The same applies to the noodle cookers, the dosing pumps for tare seasoning and the ladles used to portion broth into bowls. Each ladle is tested for capacity once a quarter, because a slightly bent handle can change the angle of the pour and the volume that ends up in the bowl.

Training the Brigade the Same Way

A recipe is only as reliable as the people following it. Both MEN-EIJI kitchens run their new starters through the same multi-week induction, beginning with three days of washing bones and observing the simmer, then progressing through tare preparation, broth tasting and finally bowl assembly under a senior cook. The training manual mirrors the recipe document and is reviewed after every service by the head chef on shift.

The brand also rotates junior cooks between the two venues on a voluntary basis, so the muscle memory of one kitchen spreads into the other. A cook who learns the rhythm of the simmer at Hiragishi BASE can carry that rhythm into Duck Ramen EIJI without recalibrating, and a cook who discovers a clever shortcut in the newer space can teach it back at the original. Furukawa believes that a kitchen team that knows each other across venues behaves like a single brigade rather than two parallel ones, and the rotation scheme enforces that feeling across shifts and seasons.

The Daily Tasting Ritual That Catches Drift

Every morning, before either kitchen opens, the broth master ladles a small cup of the day's stock and tastes it against a reference sample kept in a sealed jar from the previous week's benchmark. If the flavour sits inside a narrow acceptable range, service begins. If it drifts, the pot is adjusted with a splash of dashi, a touch more tare or an extra thirty minutes on the bone, and the tasting repeats until the cup matches the reference. Furukawa's routine each morning typically includes this tasting as both a quality check and a teaching moment, which is why guests curious about founder Jun Furukawa's day often request to join the morning cup alongside him.

This daily cup is the moment when all the systems discussed earlier converge. The recipe, the suppliers, the water, the equipment, the trained cooks and the calibrated probes all feed into that single spoonful, and the broth master's palate is the final gatekeeper. For guests who care deeply about ideal noodle texture, the same discipline governs the noodle station. The noodles are timed to the second, shocked in cold water, then warmed to a precise temperature before they meet the broth, so the bite holds through the entire bowl.

Walking into either MEN-EIJI venue should feel like stepping into a single kitchen that happens to occupy two rooms. The broth arrives in the bowl with the same cloud-like opacity, the same oceanic warmth, the same gentle pork sweetness and the same long finish that pulls you back for the next spoonful before you have set down the chopsticks. If you are planning a trip to Sapporo and want to taste the result of all these systems in person, check the opening hours on the MEN-EIJI website, book early for the dinner service at Hiragishi BASE, and arrive hungry. The kitchen has spent years building the consistency that your bowl depends on, and it is waiting.
