What is Sōmen?

Sōmen are white, thin wheat noodles typically measuring less than 1.3 mm in diameter. Unlike soba (buckwheat) or udon (thick wheat noodles), sōmen are delicate and smooth, and often served cold with a light dipping sauce. Their quick cooking time and subtle flavour make them a popular summer dish in Japan.

Ingredients for Sōmen Noodles

For this recipe, we’ll use store-bought dried sōmen noodles, which are widely available in Asian supermarkets and online. Making sōmen from scratch is quite specialised, as it involves stretching the dough rather than cutting it.

Ingredients:

200g dried sōmen noodles

Ice cubes and cold water (for chilling)

Mentsuyu dipping sauce (homemade or store-bought)

Optional toppings:

Sliced spring onions

Grated ginger

Shiso leaves

Nori (seaweed strips)

Toasted sesame seeds

Wasabi (a small amount)

For Homemade Mentsuyu Sauce

You can buy mentsuyu pre-made, but making your own is simple and allows you to control the flavour.

Ingredients:

100ml soy sauce

100ml mirin (sweet rice wine)

200ml dashi stock (kombu and bonito based)

Method:

Combine the soy sauce, mirin, and dashi in a pan. Bring to a gentle boil, then remove from heat and let it cool completely. Refrigerate before serving.

How to Cook Sōmen Noodles

Cooking sōmen properly is key to achieving the ideal smooth and bouncy texture.

Step 1: Boil Water

Bring a large pot of water to a rolling boil. Do not add salt.

Step 2: Cook the Noodles

Add the dried sōmen noodles and stir gently to prevent sticking. Cook for 2–3 minutes, or follow the package instructions.

Step 3: Drain and Rinse

Immediately drain the noodles and rinse under cold running water to remove starch and stop cooking. Use your hands to rub the noodles gently while rinsing.

Step 4: Ice Bath

Place the rinsed noodles in a bowl of ice water to chill completely. This gives sōmen its signature refreshing texture.

How to Serve Sōmen

Sōmen is traditionally served cold on a bamboo mat or tray with dipping sauce in a separate small bowl. Diners dip the noodles into the sauce before eating.

Traditional Presentation:

Drain the chilled noodles and twist small portions into neat bundles using chopsticks or a fork.

Arrange them on a chilled plate or bamboo tray.

Add a few ice cubes underneath or on the side to keep them cool.

Serve mentsuyu in a small bowl, garnished with spring onions, ginger, or your preferred toppings.
