The steam rises first. Then the smell: roasted bones, soy, something toasted. A bowl of noodle soup in Japan is both comfort and craft.
Beyond the names on a menu, the differences between ramen, udon and soba are simple to learn. Once you know them, you can order, cook and improvise with confidence.
The three noodles
| Noodle | Made from | Texture | Typical broth |
|---|---|---|---|
| Ramen | Wheat flour, water, kansui (an alkaline solution) | Springy, chewy, often wavy | Rich, from bones or fish, seasoned with soy, salt or miso |
| Udon | Wheat flour, water, salt | Thick, soft, chewy | Light, from dashi, soy and mirin |
| Soba | Buckwheat flour, often with some wheat flour | Thin, earthy, slightly firm | Light dashi, often served cold with dipping sauce |
Note on soba: many soba noodles contain wheat as well as buckwheat. If you avoid gluten, look for noodles labelled 100 percent buckwheat, sometimes called juwari.
Ramen: depth from the broth
Ramen broth is the centre of the bowl. Traditionally, it is built in layers:
- Base: pork, chicken, fish or vegetable stock, simmered for hours.
- Tare: the seasoning, usually soy sauce (shoyu), salt (shio) or miso.
- Aroma oil: a spoon of flavoured fat on top.
- Toppings: sliced pork, egg, bamboo shoots, scallions, nori.
Restaurant ramen is often high in fat and salt. At home, you can build a lighter bowl with chicken or vegetable stock and plenty of vegetables.
Udon: comfort in a simple bowl
Udon is thick, soft and mild. The classic broth is dashi seasoned with soy and mirin, with toppings such as scallions, fried tofu, tempura or a soft egg.
It is a good first noodle soup to cook at home, because the broth takes minutes if you have dashi.
Soba: lightness and aroma
Soba has a nutty, earthy flavour. It is eaten hot in a light broth, or cold on a bamboo tray with a dipping sauce, which is popular in summer. In some traditions, soba is eaten on New Year's Eve.
Buckwheat is not a type of wheat, and it is naturally gluten-free, but check the packaging for added wheat.
The broth: where the calm comes from
A calm bowl is built on a clear, balanced broth. Some key ideas:
- Dashi gives umami without heaviness. Kombu and bonito are the classic base.
- Soy sauce, mirin and a little salt season it.
- Don't boil too hard, since gentle heat keeps the broth clear.
- Taste carefully. Add seasoning in small amounts.
A simple udon bowl at home
For two bowls:
- Heat about 600 ml of dashi gently.
- Add 2 tablespoons soy sauce and 1 tablespoon mirin. Taste and adjust.
- Cook two portions of udon in a separate pot of boiling water, following the packet. Drain.
- Place noodles in bowls and pour over the hot broth.
- Top with sliced scallions and, if you like, a soft-boiled egg or a few slices of tofu.
Time: about fifteen minutes.
A lighter bowl
- Use plenty of vegetables such as spinach, mushrooms, cabbage or carrots.
- Add a protein such as egg, tofu or fish.
- Use less broth seasoning, and drink a little less of the salty broth.
- Choose smaller noodle portions and add more toppings.
Salt, and a note on health
Japanese noodle soups are often high in sodium. A restaurant bowl can contain a large share of the daily recommended amount. If you have high blood pressure, kidney disease or are advised to reduce salt, use less seasoning, leave some broth, and ask your doctor or dietitian.
Noodle soups are comfort food and part of a varied diet. They are not health food or medicine, and this article makes no health claims about them.
Eating the bowl properly
In Japan, slurping is normal and considered a way to cool the noodles and enjoy the aroma. Eat the noodles while they are hot and drink the broth from the bowl. Take your time.
Common mistakes
- Overcooking the noodles. Cook them until just done, since they keep softening in the broth.
- Cooking noodles in the broth. Starch makes it cloudy, so cook them separately.
- Over-seasoning. Taste first.
- Using boiling broth for delicate toppings. Add egg and greens at the end.
Questions readers ask
Can I make ramen without pork?
Yes. Chicken, mushroom or vegetable broths are common and satisfying.
Do I need dashi?
It helps for udon and soba. For a quick version, use instant dashi granules or a light chicken or vegetable stock.
Are instant noodles the same?
Instant noodles are a different product, often high in salt and fat. They can be improved with fresh vegetables and egg.
