Why Is Korean Bone Broth White?

Korean bone broth, known as "gamjatang," is a hearty and flavorful soup that’s gained popularity worldwide. One intriguing aspect of this traditional dish is it’s distinct milky-white appearance. The secret lies in the meticulous preparation process, which involves soaking the bones in cold water and blanching them in boiling water. This initial step ensures all impurities and traces of blood are removed, resulting in a pure and clean broth. While the timing for this recipe is provided, it’s important to note that Koreans don’t rely on clocks when creating their bone broth. Instead, they rely on their culinary intuition and experience to achieve the perfect balance of flavors. The resulting milky-white broth isn’t only visually appealing but also contributes to the rich and satisfying taste that’s made Korean bone broth a beloved culinary tradition.

Why Is Ox Bone Soup White?

The process of making ox bone soup involves a unique technique that results in a distinct and appealing white color. Unlike other bone broths, such as beef or chicken, Korean ox bone soup deliberately aims for a milky white appearance. So, what sets it apart? The secret lies in the heat level.

To obtain a clear broth, typical bone broths are prepared by gently simmering the bones over low heat. This low heat ensures that the broth remains translucent, allowing the flavors to develop without clouding the appearance. Yet, for Korean ox bone soup, a different approach is taken.

When making this particular soup, the heat level is crucially adjusted to achieve the desired white color. The bones aren’t simmered gently; instead, they’re subjected to higher heat. This higher heat helps to extract more fat and collagen from the bones, resulting in emulsions that give the broth it’s distinct color. As a result, the soup takes on a creamy white appearance that’s visually appealing.

The fats also emulsify with the gelatinous collagen found in the bones, giving the broth a thicker consistency. Additionally, the higher heat helps the flavors intensify, resulting in a robust and deeply satisfying taste.

It’s important to note that this higher heat level doesn’t mean the bones are boiled vigorously. Instead, they’re gently simmered but at a slightly higher temperature to achieve the desired results. This careful control of the heat ensures that the broth remains balanced, neither too thick nor too watery, while still attaining the sought-after white color.

By carefully adjusting the heat, the broth becomes a velvety white canvas that showcases the rich flavors extracted from the bones.

The presence of a white layer on bone broth often raises questions about it’s composition. Contrary to popular belief, this filmy substance, known as broth scum, isn’t derived from the bones but rather from the meat. Composed of denatured congealed protein, similar to the proteins in egg whites, it shouldn’t be confused with gelatin, which readily dissolves. So, what exactly causes this white stuff to form in your bone broth? Let’s delve into the science behind it.

What Is the White Stuff on Bone Broth?

The white stuff that often forms on the surface of bone broth is commonly referred to as “broth scum.”. Although it may not be the most visually appealing aspect, it’s a natural occurrence during the cooking process. Contrary to popular belief, this white substance isn’t fat but rather denatured congealed protein. It isn’t derived from the bones themselves, but rather from the meat used in making the broth.

Unlike gelatin, which dissolves when cooked, this protein-based scum appears as a result of the proteins in the meat being released and reformed during simmering. Similar to the proteins found in egg whites, these proteins become denatured and coagulate, resulting in the formation of the white substance.

While some people may wish to remove the broth scum due to it’s appearance, it’s worth noting that it doesn’t affect the flavor or quality of the broth. In fact, some might argue that leaving it intact can contribute to a richer and more flavorful broth. However, if desired, the scum can be skimmed off using a spoon or ladle.

It’s simply a result of the proteins in the meat reacting to heat and coagulating. Additionally, the scum is typically harmless and can be consumed without any adverse effects.

To summarize, the white substance that forms on bone broth is denatured congealed protein. This protein-based scum is similar to the proteins found in egg whites and contributes to the overall composition of the broth.

The Benefits of Bone Broth: Discuss the Various Health Benefits That Are Associated With Consuming Bone Broth, Such as Improved Digestion, Joint Health, and Immune Support.

Bone broth is a nourishing liquid made by simmering animal bones and connective tissues in water. It’s gained popularity due to it’s numerous health benefits. The first benefit is improved digestion. Bone broth is rich in gelatin, which helps heal and seal the gut lining, reducing inflammation and improving nutrient absorption. It also contains amino acids, such as glycine and glutamine, that support the growth of beneficial gut bacteria. Additionally, bone broth promotes joint health. It contains glucosamine, chondroitin, and collagen, which help reduce joint pain, inflammation, and stiffness. Regular consumption of bone broth can also provide immune support. It contains amino acids and minerals, like calcium and magnesium, that strengthen the immune system and support healthy immune function.

Bone broth gets it’s dark brown color from the process of roasting and caramelizing bones when making beef stock. The result is a rich, flavorful liquid that’s highly nutritious and beneficial for bone health due to it’s high gelatin content. Unlike store-bought broth, homemade bone broth is more gelatinous and dense, making it an excellent choice for those looking to support their bones and overall well-being.

Why Is Bone Broth Brown?

Bone broth is a rich and nourishing liquid that’s gained popularity due to it’s various health benefits. One of the distinctive features of bone broth is it’s brown color, which is primarily caused by the process of roasting and caramelizing bones. When bones are subjected to heat, their natural sugars and proteins undergo a chemical reaction known as the Maillard reaction, resulting in the dark brown color.

The roasting and caramelization of bones also contribute to the gelatinous texture of homemade bone broth. As the bones simmer and release collagen, a protein found in connective tissues, tendons, and cartilage, they dissolve into the liquid, giving it a thicker consistency. This gelatin content isn’t only responsible for the unique mouthfeel and taste of bone broth but also holds numerous benefits for bone health.

The gelatin in bone broth contains essential amino acids that are vital for maintaining healthy bones and joints. These amino acids, such as glycine and proline, play a crucial role in collagen synthesis and strengthening connective tissues.


In conclusion, the reasoning behind Korean bone broth being white lies in the meticulous preparation process. By soaking the bones in cold water and subsequently blanching them in boiling water, the impurities and blood are effectively removed, resulting in a milky-white broth. While precise timing may be given for the recipe, it’s important to note that Korean cooks rely on their instinct and experience, never relying solely on the clock.
