Japanese Noodle Cold Service Hiyashi Chūka and the Art of Summer Noodles

Ingredients

• 400 g fresh ramen noodles (chūka-style, kansui noodles), or 320 g dried; chilled after cooking
• For the shōyu-dare (Tokyo style)
• 45 ml soy sauce
• 30 ml rice vinegar
• 15 ml sesame oil
• 15 g sugar
• 15 ml dashi, cold
• For the goma-dare (Osaka style, alternate)
• 60 g sesame paste (white nerigoma), thinned to pourable consistency with vinegar or dashi
• 30 ml soy sauce
• 30 ml rice vinegar
• 15 ml mirin
• Toppings
• 4 eggs, made into tamagoyaki, sliced into thin strips
• 1 cucumber, julienned
• 2 tomatoes, sliced
• 120 g chashu pork, thinly sliced
• 120 g cooked ham, julienned
• 80 g prepared jellyfish (kurage), rinsed; optional

Method

1. 1
   Combine the shōyu-dare ingredients — soy sauce, rice vinegar, sesame oil, sugar, and cold dashi — in a small bowl and stir until the sugar is fully dissolved. Transfer to the refrigerator for at least 30 minutes before service. The tare should be assertively tart and slightly stronger in seasoning than seems correct at room temperature; cold service suppresses flavour perception. The tare is ready when it is fully cold, unified in flavour, and carries a clean sharp-sweet aroma of vinegar and sesame.
2. 2
   For the goma-dare alternative, whisk the sesame paste with the rice vinegar, soy sauce, and mirin, adding vinegar or cold dashi a little at a time until the mixture flows freely from a spoon. Undiluted sesame paste will seize on cold noodles; the sauce must be pourable before it goes anywhere near them. Refrigerate until fully cold.
3. 3
   Prepare all toppings and hold them refrigerated on separate plates: tamagoyaki sliced into thin strips (yellow), cucumber julienned (green), tomatoes sliced (red), chashu pork thinly sliced, ham julienned (pink), and jellyfish rinsed and drained if using. Chill the serving plates in the refrigerator at this stage.
4. 4
   Boil the ramen noodles according to their weight and type, maintaining a vigorous boil. The moment the noodles are cooked through — springy when bitten, with no raw flour taste at the centre — drain them immediately and plunge into a bowl of ice water. Rinse vigorously with both hands, rubbing the noodles to remove surface starch. This step decides the dish: noodles that are not rinsed in ice water will clump into a starch-bonded mass and cannot be recovered. The noodles are ready when they are cold to the touch, glossy, separated, and firm.
5. 5
   Drain the noodles thoroughly, shaking off excess water. Divide among the chilled plates, arranging in a flat, flowing mound — the noodles are the feature of the dish and must remain visible. The noodle base should not be buried.
6. 6
   Arrange the toppings in decorative rows or fans across the noodle base: yellow egg strips, green cucumber, red tomato, pink ham, chashu, and jellyfish if using. The colour composition — yellow, green, red, pink against white — communicates freshness and season and is as functional as it is aesthetic. Each colour group should be distinct and visible.
7. 7
   Pour the cold tare over the noodles at the table, or serve alongside for dipping. The dish is complete when noodle, topping, and tare are cold, the tare distributes evenly across the springy noodle strands, and the first mouthful is bright, tangy, and refreshing with a clean alkaline note from the kansui noodle.
