The world of Asian noodle soups is rich and diverse, offering a symphony of flavors and textures that vary greatly from region to region. Two popular contenders often compared are Tonkinese soup, hailing from Hanoi, Vietnam, and Pho, Vietnam’s national dish. While both are undeniably delicious and share a Vietnamese heritage, they are distinct culinary creations with unique characteristics. Are they the same? Absolutely not. This article delves deep into the nuances of each soup, exploring their ingredients, preparation methods, regional variations, and historical roots to definitively answer this question.
Unraveling the Origins and History
Understanding the history of a dish is crucial to appreciating its essence. Both Pho and Tonkinese soup boast compelling stories rooted in the culinary landscape of Vietnam.
The Pho Saga
Pho’s origins can be traced back to the late 19th and early 20th centuries in northern Vietnam, specifically Hanoi. It is believed to have been influenced by both Chinese and French cuisines. The name “Pho” is thought to be derived from the French “pot-au-feu,” a beef stew. Initially, Pho was primarily a breakfast dish sold by street vendors. The popularity of Pho spread throughout Vietnam and eventually worldwide, particularly after the Vietnam War. Today, Pho is considered Vietnam’s national dish and a symbol of its culinary identity. It’s a comfort food enjoyed by people of all walks of life.
Tonkinese Soup’s Hanoi Heritage
Tonkinese soup, also known as “Bún thang,” has a more refined and elaborate history, deeply intertwined with the culture of Hanoi. Unlike Pho, which initially emerged from street food culture, Bún thang was traditionally associated with Hanoi’s elite families. It was often prepared for special occasions and celebrations. The preparation of Bún thang is considered an art form, requiring meticulous attention to detail and a wide range of ingredients. The name “Bún thang” roughly translates to “rice vermicelli ladder,” referring to the intricate arrangement of ingredients atop the noodles. While Pho has achieved global recognition, Bún thang remains a cherished culinary treasure of Hanoi, often considered a more complex and sophisticated soup.
Dissecting the Ingredients: A Tale of Two Soups
The key to differentiating Tonkinese soup and Pho lies in their distinct ingredients. Each soup employs a unique combination of elements that contribute to its signature flavor profile.
Pho’s Core Components
The essence of Pho resides in its aromatic broth, typically made by simmering beef bones, ginger, star anise, cloves, and other spices for several hours. This long simmering process extracts the rich flavors from the bones and spices, creating a complex and deeply satisfying broth. Rice noodles, known as “Banh Pho,” are the foundation of the soup. These wide, flat noodles provide a delicate texture that complements the rich broth. Thinly sliced beef (usually rare or cooked) is the most common protein used in Pho, although chicken (Pho Ga) is also popular. Fresh herbs, such as cilantro, basil, and mint, along with bean sprouts, lime wedges, and chili peppers, are served as accompaniments, allowing diners to customize their bowl of Pho to their liking.
Tonkinese Soup’s Symphony of Flavors
Tonkinese soup boasts a far more diverse and intricate array of ingredients. The broth, while similar to Pho in that it uses bones for the base, is often enhanced with dried shrimp, shiitake mushrooms, and chicken bones, adding layers of umami and depth. Thin rice vermicelli noodles, known as “Bún,” are used instead of the wider “Banh Pho” noodles found in Pho. Shredded chicken, thinly sliced Vietnamese ham (Cha Lua), and fried egg crepes cut into strips are essential protein components. Shrimp floss, a unique ingredient that adds a delicate seafood flavor and textural contrast, is a signature element of Bún thang. Finely chopped scallions, cilantro, and Vietnamese coriander (Rau Ram) provide fresh herbal notes. Preserved radish (Cai Cu) and finely ground roasted rice powder (Thinh) contribute distinctive savory and nutty flavors. A small dollop of shrimp paste (Mam Tom), known for its pungent aroma, is often added for an extra layer of complexity (optional).
Preparation Techniques: Simplicity vs. Complexity
The preparation methods for Pho and Tonkinese soup reflect their contrasting histories and culinary philosophies.
Pho: A Focus on Broth and Assembly
The preparation of Pho revolves around crafting the perfect broth. This involves simmering bones and spices for an extended period, carefully skimming off any impurities to ensure a clear and flavorful broth. Once the broth is ready, assembling Pho is relatively straightforward. The noodles are blanched, placed in a bowl, topped with sliced beef or chicken, and then ladled with hot broth. The fresh herbs and other accompaniments are added at the table, allowing diners to customize their bowl. The simplicity of Pho’s assembly makes it a popular street food and restaurant dish.
Tonkinese Soup: An Art of Arrangement
The preparation of Tonkinese soup is significantly more complex and time-consuming. Each ingredient requires individual preparation, from shredding the chicken and slicing the ham to making the egg crepes and preparing the shrimp floss. The broth, as previously mentioned, involves a more diverse range of ingredients and simmering techniques. The final step, and perhaps the most crucial, is the artful arrangement of the ingredients atop the noodles. The ingredients are carefully placed to create a visually appealing and harmonious balance of flavors and textures. This meticulous arrangement is a hallmark of Bún thang and reflects its origins as a dish prepared for special occasions.
Regional Variations and Adaptations
Both Pho and Tonkinese soup have evolved over time, resulting in regional variations and adaptations that reflect local preferences and available ingredients.
Pho: A North-South Divide
Pho has two primary regional variations: Northern Pho (Pho Bac) and Southern Pho (Pho Nam). Northern Pho, originating from Hanoi, is characterized by its simpler broth, fewer herbs, and a focus on the quality of the beef. Southern Pho, influenced by the culinary traditions of southern Vietnam, tends to have a sweeter broth, a wider variety of herbs and garnishes, and the addition of sauces like hoisin and sriracha.
Tonkinese Soup: Maintaining Tradition
While Pho has seen significant regional adaptations, Tonkinese soup has largely remained true to its Hanoi roots. Variations exist, but they tend to be subtle, focusing on the quality of ingredients and the specific techniques used in their preparation. The core elements of Bún thang – the complex broth, the diverse array of ingredients, and the artful arrangement – remain consistent across different versions.
Nutritional Considerations
Understanding the nutritional profiles of Pho and Tonkinese soup can help you make informed dietary choices.
Pho primarily provides carbohydrates from the rice noodles, protein from the beef or chicken, and vitamins and minerals from the herbs and vegetables. The broth can be high in sodium, especially if prepared with commercial bouillon or excessive salt. Tonkinese soup offers a more diverse range of nutrients due to its wider array of ingredients. It provides carbohydrates from the rice vermicelli, protein from the chicken, ham, and shrimp floss, and vitamins and minerals from the herbs, vegetables, and shrimp. The broth, similar to Pho, can be high in sodium.

What are the key differences between Tonkinese soup and Pho?
Tonkinese soup and Pho, while both Vietnamese noodle soups, differ significantly in their broth and noodle types. Tonkinese broth typically features a tangy and creamy tomato-based broth, colored red from the tomatoes and annatto seeds. The noodles used are usually thick rice noodles, similar to banh canh.
Pho, in contrast, boasts a clear and fragrant broth made with beef bones, spices, and herbs. Its signature characteristic is the use of flat rice noodles, typically thinner than those found in Tonkinese soup. The overall flavor profiles are distinct, with Tonkinese offering a richer, tangy experience, and Pho delivering a more delicate and aromatic taste.
What ingredients are commonly used in Tonkinese soup?
The hallmark ingredient of Tonkinese soup is, undoubtedly, the tomato. Tomatoes are used generously in the broth-making process, lending their acidity and sweetness to the overall flavor. Annatto seeds are often used to enhance the vibrant red color of the broth, adding a subtle earthy undertone.
Besides tomatoes, key components include fish sauce, tamarind paste for added tang, and often fried tofu, shrimp, and various vegetables. Herbs like cilantro, mint, and scallions are essential for garnishing, along with a squeeze of lime to brighten the flavors further.
How does the broth preparation differ between Tonkinese and Pho?
Tonkinese broth is characterized by its tomato-based foundation, which undergoes a simmering process to develop its distinct tangy flavor. Unlike Pho, where broth clarity is paramount, Tonkinese broth is often slightly opaque due to the presence of blended tomatoes and other ingredients. The broth is typically enriched with fish sauce and tamarind for a balanced savory and sour taste.
Pho’s broth preparation relies heavily on simmering beef bones for extended periods, sometimes over several hours or even days. This process extracts the rich marrow and collagen from the bones, creating a deep, umami-rich base. A careful blend of spices like star anise, cinnamon, and cloves infuses the broth with its signature aromatic qualities, while meticulous skimming ensures clarity.
Can I easily find Tonkinese soup on a typical Vietnamese restaurant menu?
While Pho is ubiquitous on Vietnamese restaurant menus worldwide, Tonkinese soup is less commonly found. Pho’s widespread popularity has made it a staple in Vietnamese cuisine outside of Vietnam. Its readily available ingredients and simpler preparation contribute to its prevalence.
Tonkinese soup, being more regional and relying on a specific balance of tangy flavors, is often considered a more specialized dish. You’re more likely to find it in restaurants that specialize in Northern Vietnamese cuisine or those with a more extensive menu featuring regional specialties. It’s always worth checking with your local Vietnamese restaurants if they offer it, even if it’s not explicitly listed.
What are the regional origins of Tonkinese soup and Pho?
Tonkinese soup originates from Hanoi, the capital of Vietnam, and reflects the culinary traditions of Northern Vietnam. It’s a regional specialty showcasing the use of tomatoes and tangy flavors, characteristic of the region’s cuisine.
Pho, on the other hand, is also believed to have originated in Northern Vietnam, specifically near Hanoi, in the early 20th century. However, its popularity spread throughout the country and beyond, evolving with regional variations along the way.
What are the common toppings and garnishes for Tonkinese soup versus Pho?
Tonkinese soup is often topped with fried tofu, sliced tomatoes, shrimp, and sometimes fish cakes. Fresh herbs like cilantro, mint, and scallions are generously sprinkled on top, adding freshness and aroma. A squeeze of lime is also essential to balance the richness and tanginess of the broth.
Pho typically features thinly sliced beef (rare or cooked), sometimes brisket or meatballs. Bean sprouts, basil, lime wedges, and sliced chili peppers are served alongside, allowing diners to customize their bowls to their preferred level of spice and herbal flavors. Hoisin sauce and Sriracha are common condiments offered as well.
Is Tonkinese soup healthier than Pho?
Determining which soup is “healthier” depends on individual dietary needs and preferences. Tonkinese soup, with its tomato base, offers vitamins and antioxidants from the tomatoes. However, the use of fried tofu and potentially higher sodium content from fish sauce should be considered.
Pho’s broth, simmered with bones, provides collagen and minerals. Lean beef provides protein. However, the broth’s sodium content and potential for high carbohydrate intake from the noodles are factors to keep in mind. Portion control and awareness of added condiments are important for both soups.
