Hiyashi Chuka and Cold Ramen: Broth, Noodles, Toppings and Origin

Hiyashi chuka is cold ramen noodles served on a plate with a soy-vinegar or sesame dressing and strips of egg, cucumber, ham and tomato; cold ramen more broadly includes chilled soups and cold tsukemen. In a Hong Kong August it is the ramen that makes sense, and most shops run it only in summer.

What to expect. Rinsed, chilled noodles fanned on a plate; a sweet-sour soy dressing or a creamy sesame one; toppings cut into matching strips — omelette, cucumber, ham or chicken, tomato, pickled ginger, sometimes shrimp — and mustard on the side. No hot broth at all.

🍲 1. Dressing instead of broth

Hiyashi chuka has no soup: the “tare” is a dressing of soy, rice vinegar, sugar and sesame oil (shoyu-dare) or sesame paste and vinegar (goma-dare), poured over at the table. Chilled-soup ramen (hiyashi ramen) and cold tsukemen are different dishes; see tsukemen and ramen tare.

🍜 2. Noodles and toppings

Medium ramen noodles boiled, shocked in iced water and drained hard so they stay springy; toppings are julienned for even bites. See ramen noodles.

📜 3. Origin

Hiyashi chuka is a Japanese invention of the 1930s; Sendai’s Ryutei and Tokyo’s Yosuko Saikan both claim it, and it became a nationwide summer menu item in the post-war decades. The “chuka” (Chinese) in the name refers to the noodle, not a Chinese dish.

🇭🇰 4. In Hong Kong and at home

Hong Kong shops post it as a seasonal special from roughly May to September; check the seasonal trends page. It is the easiest ramen to cook in a hot flat because nothing simmers for long: hiyashi chuka for Hong Kong summer. For other cold formats see tsukemen versus ramen.

Cold does not mean low salt. The dressing is concentrated soy; a plate can carry as much sodium as a bowl of soup. Pour half the dressing first. See ramen sodium.
