Udon

What Is Udon?

Udon is thick, white, springy wheat noodles made from flour, salt, and water — no alkaline treatment, no eggs, no kansui. The technical magic is in the kneading: traditional udon is kneaded by stepping on it (in plastic bags, with feet) to develop the wheat protein bonds that create udon's signature texture. The result is glassy-smooth, slippery, with dramatic chew.

It's served in clean kelp-and-bonito dashi broth flavored with soy and mirin — completely different from ramen's heavy broth philosophy. Udon broth is meant to taste clean; udon noodles are meant to taste like wheat.

Sanuki vs Inaniwa — The Two Major Schools

• Sanuki udon (from Kagawa Prefecture on Shikoku) — Thick, square-cut, dramatic chew. The dominant Japanese style. What you get when you order "udon."
• Inaniwa udon (from Akita Prefecture in northern Japan) — Thinner, hand-stretched, more delicate. Often eaten cold. Considered the elegant counterpart.

Kagawa Prefecture is so udon-obsessed that it's nicknamed "Udon Prefecture." There are an estimated 800+ udon shops in this single small prefecture.

Common Udon Dishes

• Kake udon — Plain udon in dashi broth. The standard.
• Tempura udon — Topped with fried shrimp or vegetables
• Curry udon — Japanese curry over udon
• Yaki udon — Stir-fried udon (related to yakisoba but with udon noodles)
• Zaru udon — Cold udon with dipping sauce
• Kitsune udon — With sweet fried tofu pouches

Flavor Profile

Udon is subtle, clean, and texture-forward. The noodles taste like wheat — slightly sweet, with the chew being the dominant experience. The broth is gentle umami without aggression. It's a study in restraint.

How Udon Differs from Ramen

• Wheat treatment: Udon has no alkaline (no kansui). Ramen does.
• Noodle shape: Udon is thick, white, square-cut. Ramen is thinner, yellow, with variable shape.
• Broth philosophy: Udon broth is clear and gentle. Ramen broth is rich and layered.
• Cultural feeling: Udon is restrained, refined, daily. Ramen is bold, dramatic, special-occasion.

If ramen is loud, udon is quiet. Both are excellent — different moods.

Where to Eat Udon in the US

Specialist udon shops are rare in the US but growing:

• Marugame Udon (Japanese chain, multiple US locations)
• Tsurumaru Udon Honpo (LA, NYC)
• Ozu (LA, NJ — Mitsuwa-affiliated)
• Most Japanese restaurants serve udon as one of several offerings

For premium Inaniwa udon, look for restaurants that specifically advertise "Inaniwa style" or "hand-stretched udon."

Making Udon at Home

Fresh udon dough is achievable at home but time-intensive. Easier path:

• Dry udon (Hakubaku, Maruchan Seimen) — Sold at H Mart and Amazon. Cooks in 8-10 minutes. Good quality.
• Frozen pre-cooked udon (Sanuki brand) — Sold at H Mart and Mitsuwa. Best non-fresh option — the texture survives freezing remarkably well.
• Refrigerated fresh udon — Sold at well-stocked Asian groceries; best home option.

For the broth, dashi is the foundation:

• Dashi packets (Hondashi, Yamaki Kappo) — quick-dissolve
• From scratch — kombu + katsuobushi steeped in hot water for 10 minutes

The Slurping Rule

Like ramen, udon should be slurped. Cold udon (zaru udon) particularly — you dip the noodles into tsuyu sauce, then slurp them in one motion. The slurp aerates the noodles and brightens the flavor.
