Somen Recipes: Cool Noodles to Beat the HCMC Heat

Temperatures in Ho Chi Minh City exceed 30°C on most days throughout the year. Cold somen noodles, a Japanese summer staple, are a perfect match for the city's heat. They take just 2 minutes to boil, require minimal effort, and keep you from standing in a hot kitchen for long. This article covers somen recipes ideal for HCMC life, from basic cold somen and Vietnamese-style twists to warm nyumen soup and chanpuru stir-fry.

Basic Cold Somen

Boiling Tips

The key to great somen is in the boiling. Bring plenty of water to a boil (at least 1 liter per 100 g of somen) and add the noodles while gently separating the strands. Once it returns to a boil, do not add cold water; instead, adjust the heat and cook for 1.5 to 2 minutes. Immediately drain in a colander and rinse thoroughly under running water, rubbing to remove the starchy coating. This step is essential for that smooth, slippery texture.

Tighten with Ice Water

Since tap water in HCMC is not safe to use directly, rinse the noodles with filtered or bottled water. Soaking the rinsed somen in ice water firms them up and gives them a pleasant chewiness. Lay ice in a bowl and arrange the somen on top for a refreshing presentation.

How to Make Tsuyu and Using Store-Bought Tsuyu

Homemade Mentsuyu

Combine soy sauce, mirin, and water in a pot at a 1:1:3 ratio. Add a handful of bonito flakes and bring to a medium heat. Once boiling, reduce to low heat and simmer for about 2 minutes, then strain and let cool. Make ahead and keep it in the fridge for up to 3 days.

Quick Option: Store-Bought Tsuyu

On busy days or when you don't have time to make dashi, store-bought mentsuyu is a convenient alternative. Farmi carries Japanese brands like Yamamori tsuyu. Use the straight type as-is, or dilute the concentrated type according to the label.

Condiments Make the Difference

The condiments you add to your dipping sauce can completely change the flavor. Classics include grated ginger, chopped green onion, and ground sesame. If you can get shiso leaves or myoga, the taste becomes even more authentic.

Twists with Vietnamese Herbs and Local Vegetables

Making Use of Local Ingredients

Markets and supermarkets in HCMC are stocked with fresh herbs that are hard to find in Japan. Using them as somen toppings offers a unique twist that you won't get with traditional Japanese somen.

• Thai basil (húng quế): A sweet aroma similar to Thai basil. Tear and scatter over somen for extra freshness.
• Spearmint (húng lủi): Its clean, refreshing scent is perfect for hot days.
• Cilantro (rau mùi): A love-it-or-hate-it addition, but irresistible for fans.
• Morning glory (rau muống): Briefly blanched and served alongside, it adds texture and nutrition.
• Bean sprouts (giá đỗ): Serve raw or quickly blanched as a topping.

Somen Salad

Arrange julienned carrots, cucumbers, bell peppers, and Vietnamese herbs colorfully on top of chilled somen. For the dressing, mix mentsuyu with lime juice and a splash of fish sauce (nước mắm) for a Japanese-Vietnamese fusion dressing.

Warm Nyumen

When You Crave Warm Noodles Even in a Hot Country

When the air conditioning at the office or home leaves you feeling chilled, a warm bowl of nyumen warms you gently from the inside. Nyumen is simply somen served in hot dashi broth.

Basic Nyumen Recipe

Bring dashi broth to a boil in a pot (400 ml water with 1 teaspoon of dashi powder, or diluted store-bought tsuyu), and season with soy sauce and mirin. Boil the somen separately in another pot, drain, and transfer to the broth. To finish, gently drop in an egg and sprinkle chopped green onion. Cooking somen directly in the broth makes it slimy, so always boil separately first.

Variation Ideas

• Add shredded chicken breast for extra protein.
• Top with umeboshi (pickled plum) for a refreshing sour note.
• Add mushrooms to deepen the umami of the broth.

Chanpuru (Stir-Fried Somen)

Okinawan Wisdom in HCMC

Somen chanpuru is a beloved stir-fry from Okinawa. It is also a great way to use up leftover somen when you have boiled too much.

How to Make It

1. Boil the somen slightly firm (30 seconds less than the package instructions), rinse, and toss with a small amount of oil.
2. Heat sesame oil in a pan and stir-fry thinly sliced pork (or canned tuna).
3. Add vegetables (bean sprouts, garlic chives, carrots, etc.) and stir-fry briefly.
4. Add the somen and season with soy sauce and dashi powder.
5. Finish with a generous topping of bonito flakes and shichimi pepper to taste.

Using morning glory or green beans available in HCMC, you can enjoy a chanpuru made with local ingredients.

Why Somen Suits Tropical Living

Convenience and Shelf Life

Dried somen can be stored at room temperature for a long time. Even in HCMC's heat and humidity, keeping it in an airtight container maintains quality. The short cooking time means minimal time in a hot kitchen, a significant advantage for tropical living.

Easy to Balance Nutrition

Somen itself is a simple wheat noodle, but by varying toppings and condiments you can supplement protein, vitamins, and minerals. Paired with Vietnam's fresh vegetables and herbs, it becomes an easy-to-eat, nutritionally balanced meal even on days when the heat kills your appetite.

Versatile Cooking Methods

Cold, hot, or stir-fried: simply changing the cooking method yields entirely different dishes. Because you never get tired of it, keeping somen in stock is always handy.
