Clear Soup | Naam Sì: A Light and Nourishing Thai Delight
Share
Clear soup, or Naam Sì in Thai, is a staple in Thai cuisine, known for its light and refreshing flavours. Unlike many other Thai dishes that are heavily spiced, clear soup is mild and often enjoyed as a comforting meal, particularly during cooler months or when one seeks a simple, healthy option. Whether you’re travelling through the bustling streets of Bangkok or exploring rural Thailand, this humble soup is a common dish found in local restaurants and homes alike.
In this blog, we will delve into the history, ingredients, and health benefits of clear soup, as well as provide an easy-to-follow recipe for those looking to recreate this delicious Thai dish at home. Whether you’re a traveller interested in trying authentic Thai cuisine or a home cook eager to expand your repertoire, this guide will give you everything you need to know about clear soup in Thailand.
What Is Clear Soup (Naam Sì)?
Clear soup is a broth-based dish that is often served with a variety of vegetables, tofu, and sometimes meat or seafood. It differs from the rich, creamy coconut-based soups like Tom Kha Gai or the spicy Tom Yum by being much lighter and gentler on the palate. Soup Sì is a versatile dish that can be easily customised to include different proteins or vegetables, making it a favourite among those looking for a healthier meal option in Thailand.
Traditionally, clear soup is made with a chicken or pork broth, though vegetable broth is also a common base for vegetarians. The broth is flavoured with simple ingredients like garlic, ginger, and pepper, which add a mild aromatic quality to the soup. Ingredients like napa cabbage, carrots, tofu, and glass noodles are commonly found in clear soup, though the exact combination of vegetables can vary depending on the region or the cook’s preference.
Fun Fact: Clear soup is often served as part of a larger meal in Thailand, acting as a palate cleanser between more heavily flavoured dishes like spicy stir-fries or curries.
History of Clear Soup in Thai Cuisine
Clear soup has a long history in Thai cuisine, with its origins likely influenced by Chinese cooking methods. Many Thai dishes, especially soups and noodle dishes, have been shaped by the Chinese diaspora in Thailand. Over time, these influences blended with local Thai flavours and ingredients, creating a unique fusion of tastes that are now recognisable in dishes like clear soup.
In Thailand, clear soup is often seen as a “comfort food,” much like chicken soup in the West. It’s typically served when someone is feeling unwell or needs something gentle and easy to digest. It’s also a popular dish for families to enjoy during evening meals, providing nourishment without being overly filling.
Nutritional Benefits of Clear Soup
One of the reasons clear soup is so popular in Thailand is due to its health benefits. It’s low in calories and fat, making it an excellent option for those looking to maintain a healthy diet. The soup’s light broth base is packed with essential vitamins and minerals from the vegetables and protein sources included in the dish.
For those watching their salt intake, clear soup can be made with low-sodium broth and without added fish sauce, making it a versatile dish for various dietary needs. The soup is also hydrating and soothing, making it a great choice during hot weather or when recovering from illness.
Here’s a breakdown of the nutritional benefits:
• Low in calories: Clear soup typically contains between 100-150 calories per serving, depending on the ingredients used.
• High in vitamins: The vegetables in clear soup, such as carrots and cabbage, provide vitamins A and C, which are essential for immune support.
• Protein-packed: Adding tofu, chicken, or shrimp can boost the protein content of the soup, aiding in muscle repair and growth.
• Hydration: As a broth-based dish, clear soup helps with hydration, especially during Thailand’s hot and humid seasons.
Fun Fact: Clear soup is a popular choice for those practising mindfulness during meals, as its simplicity encourages slow, thoughtful eating and appreciation of the subtle flavours.
How to Make Thai Clear Soup (Naam Sì)
Making clear soup at home is incredibly easy, and it requires only a handful of ingredients. This dish is perfect for those who are new to Thai cooking, as it doesn’t require any hard-to-find spices or complicated techniques.
Ingredients:
• 1 litre chicken or vegetable broth (low-sodium recommended)
• 2-3 cloves garlic, minced
• 1 tablespoon fresh ginger, thinly sliced
• 1 tablespoon soy sauce (or fish sauce, for non-vegetarians)
• 1 cup napa cabbage, roughly chopped
• 1 large carrot, thinly sliced
• 1 block of tofu, cubed (or substitute with sliced chicken or shrimp)
• 50 grams glass noodles (optional)
• 1-2 spring onions, sliced
• A pinch of white pepper
• Fresh coriander (optional, for garnish)
Instructions:
1. Prepare the Broth: In a medium pot, bring the broth to a gentle boil. Add the minced garlic and sliced ginger, and let it simmer for about 5-7 minutes to infuse the flavours into the broth.
2. Add the Vegetables: Stir in the napa cabbage and carrots. Let them cook in the broth for another 5 minutes until they begin to soften but still retain some crunch.
3. Protein: If you’re using tofu, add it to the pot and let it simmer for 3-4 minutes. If you’re using chicken or shrimp, cook them until they are fully done (about 5-7 minutes for chicken, 3 minutes for shrimp).
4. Noodles: If you’re adding glass noodles, soak them in warm water for a few minutes until they soften, then drain and add them to the soup.
5. Season: Add the soy sauce or fish sauce, and a pinch of white pepper. Taste and adjust the seasoning as necessary.
6. Finish with Garnish: Just before serving, stir in the spring onions and garnish with fresh coriander if desired.
7. Serve: Ladle the soup into bowls and enjoy it hot, either on its own or alongside other Thai dishes.
Fun Fact: In Thailand, clear soup is sometimes served alongside rice for a more filling meal. The broth can be poured over the rice, creating a heartier dish known as “khao tom” or rice soup.
Variations of Thai Clear Soup
While the above recipe is a classic version of Thai clear soup, there are many variations that you can try depending on your personal preferences or dietary restrictions. Here are a few ideas:
1. Vegetarian Clear Soup: Substitute the chicken broth with vegetable broth and add a variety of mushrooms like shiitake or oyster mushrooms for a rich umami flavour.
2. Spicy Clear Soup: For those who enjoy a bit of heat, add a few slices of bird’s eye chilli or a dash of chilli oil to the broth.
3. Seafood Clear Soup: Swap out the tofu or chicken for shrimp, squid, or a combination of seafood for a coastal twist on the traditional recipe.
4. Herbal Clear Soup: Incorporate fresh Thai herbs like lemongrass or kaffir lime leaves for an aromatic variation of the dish.
