Miso Salmon
Silky miso-glazed salmon fillet with a caramelised crust — elegant Japanese simplicity at its finest.
Chef's Critical Note
Blanch the bones in boiling water for 10 minutes and rinse thoroughly before the long broth cook. Skipping this step leaves impurities in the broth that produce a grey, bitter, muddy result instead of the signature creamy white tonkotsu.
The Story
Born in Fukuoka, beloved by the world
Tonkotsu ramen was born in Kurume, Fukuoka Prefecture, in 1937 — a happy accident when a cook left pork bones simmering too long over high heat. The result was a milky, opaque, intensely rich broth unlike anything that had come before. Fukuoka's ramen culture exploded, and the city's famous yatai (street food stalls) spread tonkotsu across Japan and eventually the world.
The genius of tonkotsu lies in its simplicity and its patience. There are no complex spice blends, no elaborate techniques — just pork bones, water, heat, and time. The collagen from the trotters and marrow bones emulsifies into the broth over 10–12 hours of vigorous boiling, creating that signature creamy, almost viscous consistency that coats every strand of noodle.
The tare — a concentrated seasoning sauce — is stirred into each bowl individually, allowing the cook to adjust saltiness per serving. The chashu pork belly, marinated soft-boiled egg (ajitsuke tamago), bamboo shoots, nori, and spring onions are not garnishes — they are essential components of a precisely composed bowl. Every element earns its place.
The Method
Step-by-step technique
-
1Blanch and clean the bones
Place pork trotters, neck bones, and marrow bones in a large pot. Cover with cold water and bring to a vigorous boil. Cook for 10 minutes — the water will turn grey and foamy. Drain completely, then rinse every bone under cold running water, scrubbing away any dark residue or marrow fragments. This step is non-negotiable for a clean, white broth.
-
2Build the tonkotsu broth
Return the cleaned bones to the pot with fresh cold water. Bring to a boil over high heat, then maintain a vigorous rolling boil — not a gentle simmer. The aggressive boil is what emulsifies the collagen and fat into the broth, creating the milky white colour. Add halved onion (charred directly over a flame), ginger, garlic, and spring onion whites. Cook uncovered for 10–12 hours, topping up with boiling water as needed to keep bones submerged. Strain through a fine-mesh sieve.

3Prepare the chashu pork belly
Roll a 600g slab of pork belly tightly into a cylinder and tie with kitchen twine at 3cm intervals. Sear in a hot pan with a little oil until deeply browned on all sides. Transfer to a snug pot or zip-lock bag with soy sauce, mirin, sake, and sugar. Braise in the oven at 160°C for 2.5 hours until tender but still sliceable. Cool in the braising liquid — this liquid becomes your tare. Refrigerate overnight for clean slices.
-
4Make the tare (seasoning sauce)
Combine the chashu braising liquid with additional soy sauce, mirin, and a splash of sake in a small saucepan. Simmer gently for 10 minutes until slightly reduced and intensified. This is your tare — add 2–3 tablespoons per bowl of broth to season. Taste and adjust; the tare should be intensely salty and deeply savoury, as it seasons the entire bowl.
-
5Marinate the soft-boiled eggs (ajitsuke tamago)
Bring a pot of water to a rolling boil. Lower eggs gently and cook for exactly 6 minutes 30 seconds for a jammy, orange yolk. Transfer immediately to an ice bath for 5 minutes, then peel carefully. Submerge in a mixture of soy sauce, mirin, and water (2:1:3 ratio) for at least 4 hours — overnight is ideal. The eggs will turn a beautiful mahogany brown with a silky, custard-like yolk.
-
6Prepare toppings
Slice the chilled chashu into 1cm rounds and sear briefly in a hot pan until caramelised on one side. Blanch bean sprouts in boiling water for 30 seconds. Slice spring onions finely on the diagonal. Drain and rinse bamboo shoots. Cut nori sheets into rectangles. Prepare a small bowl of toasted sesame seeds, a jar of mayu (blackened garlic oil) if using, and a bottle of sesame oil for finishing.
-
7Cook the noodles
Bring a large pot of unsalted water to a vigorous boil. Cook fresh ramen noodles for 1–2 minutes (dried for 3–4 minutes) until just tender with a slight chew — al dente is essential. Drain and shake off excess water. Ramen noodles absorb broth quickly, so cook to order and serve immediately.
-
8Assemble and serve
Heat the tonkotsu broth to a rolling boil. Add 2–3 tablespoons of tare to each warmed bowl. Ladle over 350–400ml of boiling broth and stir to combine. Add the noodles. Arrange 2–3 slices of chashu, half a marinated egg (sliced to reveal the yolk), bamboo shoots, bean sprouts, and nori. Finish with spring onions, sesame seeds, a drizzle of sesame oil, and a small spoonful of mayu if using. Serve immediately — ramen waits for no one.
Chef's Notes
Tips for perfection
Trotters for Collagen
Pork trotters are essential — they contain the highest concentration of collagen, which emulsifies into the broth and creates the signature creamy, viscous texture. Never substitute with lean cuts.
Boil, Don't Simmer
Tonkotsu requires a vigorous rolling boil for the full cook time. A gentle simmer produces a clear, light broth — beautiful for other styles, but wrong for tonkotsu. The aggressive heat is what creates the milky emulsion.
Egg Timing is Everything
6 minutes 30 seconds exactly for a jammy yolk. Use room-temperature eggs, lower them gently into boiling water, and transfer immediately to ice water. Even 30 seconds over will firm the yolk and ruin the effect.
Fresh Noodles Only
Seek out fresh or frozen ramen noodles from a Japanese grocery. The alkaline (kansui) noodles have a distinctive springy texture and yellow colour that dried substitutes cannot replicate. They make an enormous difference.
Mayu — Black Garlic Oil
Mayu is made by blending charred garlic with sesame oil until completely black. A small spoonful stirred into the bowl adds a smoky, bitter depth that is the secret weapon of Fukuoka ramen shops. Make a batch and refrigerate for weeks.
Make Ahead Strategy
The broth, chashu, tare, and marinated eggs all improve overnight. Make everything the day before, refrigerate separately, and assembly takes just 10 minutes. The broth fat will solidify on top — simply lift it off before reheating.
