Shoyu
A soy-sauce base, clear and saline. The most precise broth: plenty of spoon, few condiments. Ideal for a first ramen.

Homemade ramen broth
A ramen always begins with its broth. At Iwao, we draw it ourselves, every day, on rue Sainte in Marseille: hours of slow simmering before it reaches the bowl, piping hot, beneath the noodles. Here is how this heart of the dish is made, and what sets it apart.
The heart of the bowl
It all starts with the broth
In a ramen-ya, the broth is not a side: it is the dish. Everything else — noodles, toppings, seasoning — falls into place around it. A failed broth cannot be fixed at the table, and a good one needs almost nothing. That is why we draw it in-house at Iwao, from bones, poultry or vegetables depending on the recipe, and let it simmer as long as it takes to stand on its own.
At the bottom of the bowl, before the broth, sits the tare: a concentrated seasoning base — soy, miso or salt — that signs the flavour without ever showing. The broth wakes it up, the noodles rest on top, the toppings close the composition. Each layer has its place and its role. To understand the broth is to understand why you taste the soup first, with the spoon, before touching the noodles.
The bases
Four broths, four characters
One craft, different temperaments. Each base is a way of approaching the bowl — from the clearest to the most enveloping.
Miso
Round, dense, gently sweet. A broth that wraps around you — alternate often with vegetables and spring onion to keep the palate awake.
Tonkotsu
Pork bones simmered long into a milky, rich broth. The most generous: powerful and comforting, it looks for breathing space in fresh toppings.
Plant-based
Drawn from vegetables and mushrooms, delicate and clean. Treat it almost like a consommé: little to add, plenty of spoon, everything to listen to.
The long game
Hours of simmering
What gives a broth its depth is time. You do not rush it: bones, aromatics and vegetables give up slowly what they have to give, over a low flame, for hours. That patient simmer turns a handful of simple ingredients into a dense, aromatic soup that can carry the whole bowl. Nothing replaces those hours — no shop-bought stock, no shortcut.
This slowness in the kitchen explains the speed at the table. A broth worked so long is served piping hot, because heat keeps the noodles firm and lifts the aroma. It is also why the bowl reaches you the second it is plated, without waiting for the rest of the order: the best moment for a ramen is now.
The plating
From broth to bowl
Once the broth is ready, the bowl is built in a precise order. The tare at the bottom, the piping-hot broth on top, the alkaline noodles laid taut, then the toppings placed one by one — chashu, marinated egg, nori, spring onion, bamboo shoots. That plating is not decorative: it decides what you taste first, and the contrasts that will pace the bowl.
The noodles, served firm, keep cooking in the broth from the moment they go in: that is what gives ramen its short life and its joyful urgency. Taste the soup on its own first, with the spoon, then move into the alternation — a few noodles, a sip of broth, a topping. The broth stays the through-line, the one you meet with every mouthful.
The seasoning base at the bottom of the bowl. Invisible, but it signs the flavour.
Drawn in-house, poured piping hot. The heart of the dish, the part that took the most work.
Al dente noodles, chashu, egg, nori, spring onion. Each topping is a contrast, not a filler.
At Iwao
The broth in front of you
At 27 rue Sainte in Marseille, the kitchen is open: you watch the broths finish simmering and the bowl leave for your table the instant it is plated. The Tokyo-alley décor, the lanterns and the manga are there for before and after; during those few minutes, there is only the bowl, hot, exactly as it was served.
If it is your first ramen, say so: the team will point you to a suitable broth and show you how to eat it. The whole Iwao menu revolves around these house-drawn bases — it is the best place to start.
FAQ
Frequently asked questions
What makes a good ramen broth?
Time and the base. A good broth is drawn slowly, over hours, from bones, poultry or vegetables, then paired with a tare — soy, miso or salt — at the bottom of the bowl. That balance, not a last-minute addition, is what gives the bowl its depth.
Is Iwao’s broth homemade?
Yes. The broths are drawn in-house at Iwao, on rue Sainte in Marseille, and simmered as long as needed before service. The kitchen is open: you can watch them finish cooking during your meal.
What is the difference between shoyu, miso and tonkotsu?
Shoyu is a clear, saline soy-sauce broth, miso is rounder and denser, tonkotsu is a milky broth of long-simmered pork bones. The tare and the cooking change, but the logic is the same: the broth carries the bowl.
Why is the broth served so hot?
Heat keeps the noodles firm and releases the aroma. Ramen broth is therefore served very hot, often more than a European soup. You do not blow on it in the bowl: you lift the noodles and slurp them, and the air does the rest.
Do you have to finish the broth?
It is a fine compliment, never an obligation. The broths are rich and nobody will judge you for leaving some. Many taste the soup on its own with the spoon first, before even touching the noodles.
