Anchovies are a staple ingredient in many cuisines, particularly in Mediterranean and Italian cooking. These small, oily fish are known for their intense umami flavor and are often used to add depth and richness to various dishes. However, anchovies can be quite salty and overpowering, which is why many chefs and home cooks soak them in milk before using them in recipes. But have you ever wondered why soaking anchovies in milk is so effective? In this article, we’ll delve into the science behind this technique and explore its benefits.
The Science Behind Soaking Anchovies in Milk
Soaking anchovies in milk is a simple yet effective way to reduce their saltiness and bitterness. But what exactly happens when you submerge these tiny fish in milk? To understand the science behind this technique, let’s take a closer look at the composition of anchovies and milk.
The Composition of Anchovies
Anchovies are small, oily fish that are rich in protein, fat, and salt. They contain a high concentration of glutamates, which are amino acids that are responsible for their umami flavor. Anchovies also contain a significant amount of sodium, which is absorbed from the seawater they inhabit. This high sodium content is what makes anchovies so salty and overpowering.
The Composition of Milk
Milk, on the other hand, is a complex liquid that contains a mixture of water, carbohydrates, proteins, and fats. It also contains a number of minerals, including calcium, phosphorus, and potassium. Milk is slightly acidic, with a pH level of around 6.5-6.7.
The Chemistry of Soaking Anchovies in Milk
When you soak anchovies in milk, several chemical reactions occur that help to reduce their saltiness and bitterness. Here are some of the key reactions that take place:
- Casein binding: The casein proteins in milk bind to the glutamates in anchovies, reducing their umami flavor and bitterness.
- Sodium removal: The acidity in milk helps to break down the sodium ions in anchovies, making them more soluble and easier to remove.
- Fat emulsification: The fats in milk help to emulsify the oils in anchovies, making them more stable and less likely to separate.
The Benefits of Soaking Anchovies in Milk
Soaking anchovies in milk has several benefits that make it a popular technique among chefs and home cooks. Here are some of the advantages of using this method:
Reduced Saltiness
One of the main benefits of soaking anchovies in milk is that it reduces their saltiness. This is especially useful when using anchovies in dishes where you don’t want a strong salty flavor. By soaking anchovies in milk, you can reduce their sodium content and create a more balanced flavor profile.
Improved Texture
Soaking anchovies in milk also helps to improve their texture. The acidity in milk helps to break down the proteins in anchovies, making them softer and more palatable. This is especially useful when using anchovies in dishes where you want a smooth, creamy texture.
Enhanced Flavor
Soaking anchovies in milk can also enhance their flavor. The casein proteins in milk help to bind to the glutamates in anchovies, reducing their bitterness and umami flavor. This creates a more balanced flavor profile that is less overpowering and more nuanced.
How to Soak Anchovies in Milk
Soaking anchovies in milk is a simple process that requires just a few ingredients and some patience. Here’s a step-by-step guide to soaking anchovies in milk:
Ingredients

So next time you’re cooking with anchovies, give this technique a try and see the difference it can make.
What is the purpose of soaking anchovies in milk?
Soaking anchovies in milk is a common practice in many cuisines, particularly in Mediterranean and Italian cooking. The primary purpose of this process is to reduce the saltiness and bitterness of the anchovies, making them more palatable and versatile for use in various recipes. By soaking the anchovies in milk, the lactose and casein in the milk help to break down the proteins and fats in the anchovies, resulting in a milder flavor and a more delicate texture.
The milk also helps to rehydrate the anchovies, which can become dry and brittle due to the salting process. This rehydration process makes the anchovies more pliable and easier to use in cooking. Additionally, the milk can help to remove some of the impurities and excess salt from the anchovies, resulting in a cleaner and more refined flavor. Overall, soaking anchovies in milk is a simple yet effective way to enhance their flavor and texture, making them a more enjoyable ingredient to work with.
What type of milk is best for soaking anchovies?
The type of milk used for soaking anchovies can affect the final flavor and texture of the anchovies. Whole milk is generally considered the best option, as it contains a higher percentage of fat and protein than skim milk or low-fat milk. The fat and protein in whole milk help to break down the proteins and fats in the anchovies more effectively, resulting in a creamier and more tender texture.
However, other types of milk can also be used, such as almond milk or soy milk, for those who are lactose intolerant or prefer a non-dairy option. It’s worth noting that these alternative milks may not be as effective at breaking down the proteins and fats in the anchovies, and may result in a slightly different flavor and texture. Ultimately, the choice of milk will depend on personal preference and dietary needs.
How long should anchovies be soaked in milk?
The length of time that anchovies should be soaked in milk can vary depending on the desired level of flavor and texture. Generally, it’s recommended to soak the anchovies for at least 30 minutes to an hour, but they can be soaked for several hours or even overnight for a more intense flavor.
The longer the anchovies are soaked, the milder they will become, as the milk will continue to break down the proteins and fats. However, it’s worth noting that over-soaking can result in a loss of flavor and texture, so it’s best to monitor the anchovies and adjust the soaking time accordingly. A good rule of thumb is to check the anchovies after 30 minutes and adjust the soaking time based on their texture and flavor.
Can anchovies be soaked in other liquids besides milk?
Yes, anchovies can be soaked in other liquids besides milk, such as water, wine, or olive oil. However, milk is generally considered the best option due to its high fat and protein content, which helps to break down the proteins and fats in the anchovies.
Other liquids, such as water or wine, may not be as effective at breaking down the proteins and fats, and may result in a less tender texture. Olive oil, on the other hand, can be used to add flavor to the anchovies, but it may not be as effective at breaking down the proteins and fats. Ultimately, the choice of liquid will depend on personal preference and the desired flavor and texture.

Can I reuse the milk used for soaking anchovies?
It’s generally not recommended to reuse the milk used for soaking anchovies, as it may have absorbed some of the impurities and excess salt from the anchovies. Reusing the milk could result in a less flavorful and less textured final product.
However, the milk can be used as a base for other recipes, such as sauces or soups, where the flavor of the anchovies can be beneficial. It’s worth noting that the milk may have a strong umami flavor, so it’s best to use it in recipes where this flavor will be complementary. Ultimately, the decision to reuse the milk will depend on personal preference and the desired flavor and texture of the final product.
Are there any safety concerns when soaking anchovies in milk?
There are some safety concerns to be aware of when soaking anchovies in milk, particularly with regards to food safety. Anchovies are a high-risk food for contamination, and soaking them in milk can create an environment where bacteria can grow.
It’s essential to use fresh and high-quality anchovies, and to store them in the refrigerator at a temperature below 40°F (4°C) during the soaking process. It’s also crucial to use clean equipment and utensils when handling the anchovies and milk, and to discard any leftover milk or anchovies that have been at room temperature for too long. By following proper food safety guidelines, you can minimize the risk of contamination and enjoy your soaked anchovies safely.
