When it comes to cooking liver, there are strong opinions on whether or not it should be soaked before cooking. Some swear by the practice, claiming it removes impurities and bitterness, while others dismiss it as an unnecessary step. But what’s the truth? Should liver be soaked before cooking, or is it just a myth with no scientific backing? In this article, we’ll dive into the world of liver cooking and explore the pros and cons of soaking liver before cooking.
The History of Soaking Liver
Soaking liver before cooking is a technique that dates back centuries. In the past, livers were often perceived as being “impure” and in need of cleansing before consumption. This perception stemmed from the liver’s role as a filter for the body, removing toxins and waste from the blood. The thinking was that these toxins would be released into the cooking liquid if not properly removed beforehand.
In traditional European cuisine, soaking liver in milk or acidic liquids like vinegar or lemon juice was a common practice. This step was believed to not only remove impurities but also tenderize the liver, making it more palatable. The practice was also thought to help reduce the strong, gamey flavor associated with liver.
The Science Behind Soaking Liver
So, does soaking liver really make a difference? Let’s look at the science behind this practice.
Liver’s Unique Composition
Liver is a unique organ in that it’s responsible for filtering the blood and removing toxins, heavy metals, and other impurities. As a result, it contains a high concentration of these substances. When cooked, these impurities can be released into the cooking liquid, affecting the flavor and texture of the liver.
The Role of Proteins and Enzymes
Liver contains a high concentration of proteins and enzymes, including catalase, which breaks down hydrogen peroxide into oxygen and water. When liver is cut or chopped, these proteins and enzymes are released, leading to the formation of compounds that contribute to bitterness and off-flavors.
The Effect of Soaking on Liver
Soaking liver can help to:
- Reduce the release of impurities and toxins into the cooking liquid
- Break down proteins and enzymes, making the liver more tender and palatable
- Remove excess blood and impurities, resulting in a milder flavor
However, it’s essential to note that the effectiveness of soaking liver depends on various factors, including:
- The type of liver being used (beef, chicken, or pork liver may respond differently to soaking)
- The soaking time and liquid used (milk, vinegar, or lemon juice can have varying effects)
- The cooking method employed (grilling, sautéing, or braising can affect the final result)

What is the purpose of soaking liver before cooking?
Soaking liver before cooking is a common practice that serves several purposes. One reason is to remove impurities and bitterness from the liver, resulting in a milder flavor and texture. Additionally, soaking can help to rehydrate the liver, making it more tender and easier to cook.
Soaking liver can also help to remove any excess blood or sediment that may be present on the surface of the organ. This is especially important for livers that have not been properly cleaned and prepared before sale. By soaking the liver, you can remove any impurities and ensure that your final dish is safe to eat and free of off-flavors.
How long should I soak the liver before cooking?
The length of time you should soak liver before cooking can vary depending on personal preference and the type of liver you are using. Some recipes recommend soaking the liver for as little as 30 minutes, while others suggest soaking for several hours or even overnight. In general, a soaking time of around 1-2 hours is a good starting point.
It’s also important to note that the soaking time may vary depending on the acidity of the soaking liquid. For example, if you are using a highly acidic liquid like lemon juice or vinegar, you may want to soak the liver for a shorter period of time to avoid over-tenderizing the meat. On the other hand, if you are using a milder liquid like milk or water, you may be able to soak the liver for a longer period of time without affecting its texture.
