When it comes to cooking Japanese eggplant, one of the most debated topics is whether or not it needs to be salted. This practice, often referred to as “degorging,” has been a staple in many culinary traditions for centuries. But what exactly is the purpose of salting eggplant, and is it really necessary for Japanese varieties? In this article, we’ll delve into the history and science behind salting eggplant, explore the characteristics of Japanese eggplant, and provide guidance on whether or not this step is essential for achieving the best flavor and texture.
Understanding the Purpose of Salting Eggplant
Salting eggplant is a process that involves sprinkling salt over the sliced or chopped vegetable to draw out its moisture. This technique has been used for centuries to remove excess water, reduce bitterness, and improve the overall texture of the eggplant. The science behind it lies in the fact that eggplant contains a high amount of water and a type of compound called solanine, which can give it a bitter taste. By salting the eggplant, the salt helps to break down the cell walls, releasing the excess water and some of the solanine, resulting in a more balanced flavor and a less soggy texture.
The History of Salting Eggplant
The practice of salting eggplant originated in the Mediterranean region, where eggplant has been a staple ingredient for thousands of years. The ancient Greeks and Romans used salt to preserve vegetables, including eggplant, and this technique was later adopted by other cultures. In Italy, for example, salting eggplant is a common practice, especially when making dishes like eggplant parmesan. The salt helps to remove excess moisture, which can make the eggplant more susceptible to crumbling when cooked.
Characteristics of Japanese Eggplant
Japanese eggplant, also known as nasu, is a popular variety of eggplant that is native to East Asia. It is characterized by its slender shape, delicate skin, and sweet, tender flesh. Compared to other varieties of eggplant, Japanese eggplant has a lower water content and a milder flavor, which makes it an ideal choice for a variety of dishes, from stir-fries to grilled or roasted preparations. One of the key differences between Japanese eggplant and other varieties is its lower solanine content, which means it tends to be less bitter and less likely to require salting.
The Debate Over Salting Japanese Eggplant
Given the unique characteristics of Japanese eggplant, the question remains whether or not it needs to be salted. Some chefs and home cooks swear by the practice, claiming that it helps to remove excess moisture and improve the texture. Others argue that salting is unnecessary, as Japanese eggplant is already relatively dry and sweet. To settle this debate, let’s examine the arguments for and against salting Japanese eggplant.
Arguments For Salting Japanese Eggplant
While Japanese eggplant may have a lower water content than other varieties, it can still benefit from a light salting. A light dusting of salt can help to bring out the natural sweetness of the eggplant and enhance its flavor. Additionally, if you’re planning to cook the eggplant using a method that involves high heat, such as grilling or stir-frying, a quick salting can help to remove excess moisture and prevent the eggplant from becoming too soggy.
Arguments Against Salting Japanese Eggplant
On the other hand, some argue that salting Japanese eggplant is unnecessary and can even be detrimental to its flavor and texture. Over-salting can lead to a loss of the eggplant’s natural sweetness and a bitter taste, which defeats the purpose of cooking with this variety in the first place. Additionally, if you’re using a cooking method that involves low heat, such as braising or roasting, the eggplant is unlikely to release excess moisture, making salting unnecessary.

So, does Japanese eggplant need to be salted? The answer is not a simple yes or no. It ultimately depends on the cooking method, personal preference, and the specific recipe you’re using. If you do decide to salt your Japanese eggplant, here are some tips to keep in mind:
To salt Japanese eggplant, simply slice or chop it into the desired shape, sprinkle both sides with a light dusting of salt, and let it sit for 10-15 minutes. After this time, rinse the eggplant under cold running water to remove excess salt, and pat it dry with paper towels before cooking. This process can help to remove excess moisture and bring out the natural sweetness of the eggplant.
Alternative Methods for Preparing Japanese Eggplant
If you’re looking for alternative methods for preparing Japanese eggplant, there are several options you can consider. One approach is to brush the eggplant with oil and season with herbs and spices before cooking. This can help to add flavor and texture without the need for salting. Another option is to use a marinade or sauce to add moisture and flavor to the eggplant.

What is the purpose of salting Japanese eggplant?
The practice of salting Japanese eggplant, also known as nasu, is a long-standing culinary tradition in Japanese cooking. The primary purpose of salting is to remove excess moisture from the eggplant, making it easier to cook and enhancing its texture. By drawing out the water content, salting helps to reduce the bitterness and astringency often associated with eggplant, resulting in a sweeter and more palatable flavor. This step is particularly crucial when preparing dishes where the eggplant will be stir-fried, grilled, or braised, as it helps the vegetable to cook more evenly and prevents it from becoming soggy or mushy.
The process of salting Japanese eggplant involves sprinkling coarse salt over the cut or sliced vegetable and letting it sit for a specified period, usually between 15 to 30 minutes. During this time, the salt helps to break down the cellular structure of the eggplant, allowing the water to be drawn out. After the salting process, the eggplant is typically rinsed with cold water to remove excess salt, and then patted dry with paper towels to remove any remaining moisture. This step is essential to prevent the eggplant from becoming too salty and to prepare it for cooking. By following this simple yet effective process, cooks can unlock the full potential of Japanese eggplant and create a wide range of delicious and authentic dishes.
Can I skip the salting step when cooking Japanese eggplant?
While it is technically possible to skip the salting step when cooking Japanese eggplant, it is not recommended, especially if you want to achieve the best possible results. Salting plays a critical role in removing excess moisture and bitterness from the eggplant, which can significantly impact the overall flavor and texture of the dish. Without salting, the eggplant may become soggy or bitter, even if it is cooked properly. Moreover, some recipes, such as Japanese stir-fries or braises, rely heavily on the salting step to create a balanced and harmonious flavor profile.
That being said, there are some instances where you can skip the salting step, such as when using Japanese eggplant in a dish where it will be cooked for an extended period, like a stew or a braise. In these cases, the long cooking time will help to break down the cellular structure of the eggplant and remove excess moisture, making the salting step less necessary. However, for most Japanese eggplant recipes, salting is an essential step that should not be omitted. By taking the time to salt your Japanese eggplant, you will be rewarded with a more flavorful and textured dish that showcases the unique characteristics of this versatile vegetable.
How long should I salt Japanese eggplant for optimal results?
The ideal salting time for Japanese eggplant can vary depending on the specific recipe, the size and thickness of the eggplant slices, and personal preference. Generally, a salting time of 15 to 30 minutes is recommended, as this allows for sufficient moisture removal without making the eggplant too salty. For thinner slices or smaller eggplant pieces, a shorter salting time of 10 to 15 minutes may be sufficient, while thicker slices or larger pieces may require 30 to 40 minutes.
It is essential to monitor the eggplant during the salting process to avoid over-salting or under-salting. You can check the eggplant’s moisture level by gently pressing on the surface with your finger; if it feels soft and yielding, it is ready to be rinsed and cooked. If you prefer a milder flavor, you can reduce the salting time, while those who like a stronger umami taste can increase the salting time. Remember to always rinse the eggplant thoroughly with cold water after salting to remove excess salt and prepare it for cooking.
Will salting Japanese eggplant remove all its nutrients?
Salting Japanese eggplant can help to remove some of the bitter compounds and excess moisture, but it will not completely remove all the nutrients from the vegetable. Japanese eggplant is an excellent source of vitamins, minerals, and antioxidants, including vitamin C, potassium, and fiber. While some water-soluble vitamins like vitamin C and B vitamins may be lost during the salting and rinsing process, the eggplant will still retain many of its nutritional benefits.
In fact, salting can help to make the eggplant’s nutrients more bioavailable by breaking down the cellular structure and releasing the enzymes that aid in digestion. To minimize nutrient loss, it is recommended to use a gentle salting process, rinse the eggplant quickly and thoroughly, and cook it using methods that help retain its nutrients, such as steaming or stir-frying. By taking these steps, you can enjoy the nutritional benefits of Japanese eggplant while still achieving the desired flavor and texture.
Can I use other types of salt for salting Japanese eggplant?
While any type of salt can be used for salting Japanese eggplant, it is recommended to use a coarse, flaky salt or sea salt, as these types of salt are less likely to penetrate too deeply into the vegetable. Table salt, on the other hand, is finer and more dense, which can make it harder to rinse off and may result in an over-salted eggplant. Coarse salt or sea salt is also less processed and may contain more mineral impurities, which can help to bring out the natural flavor of the eggplant.
In Japanese cuisine, a type of salt called “kombu salt” or ” dashi salt” is sometimes used for salting eggplant. This type of salt is made by mixing sea salt with dried kelp or seaweed, which gives it a rich, umami flavor. Kombu salt is an excellent choice for salting Japanese eggplant, as it can add depth and complexity to the dish without making it too salty. However, if you don’t have access to kombu salt, a good-quality sea salt or kosher salt will also work well.
Is salting Japanese eggplant necessary for all recipes?
No, salting Japanese eggplant is not necessary for all recipes. Some dishes, such as Japanese-style curries or stews, may not require salting, as the cooking liquid and spices will help to balance the flavor of the eggplant. Additionally, if you are using a variety of Japanese eggplant that is known for its sweetness and low bitterness, such as the “Fairy Eggplant” or “Hansel” variety, you may be able to skip the salting step.
However, for most Japanese eggplant recipes, salting is an essential step that helps to remove excess moisture, bitterness, and astringency. This is particularly important for dishes where the eggplant will be cooked quickly, such as stir-fries or grilled dishes, as the salting step can help to create a tender and flavorful texture. If you are unsure whether to salt your Japanese eggplant, it is always best to err on the side of caution and follow the recipe instructions or consult with an experienced cook.
Can I salt Japanese eggplant ahead of time and store it in the refrigerator?
Yes, you can salt Japanese eggplant ahead of time and store it in the refrigerator, but it’s essential to follow proper food safety guidelines to prevent spoilage and foodborne illness. After salting the eggplant, make sure to rinse it thoroughly with cold water to remove excess salt, and then pat it dry with paper towels to remove excess moisture. Wrap the eggplant tightly in plastic wrap or aluminum foil and store it in the refrigerator at a temperature below 40°F (4°C).
When storing salted Japanese eggplant in the refrigerator, it’s crucial to use it within a day or two, as the eggplant can become soggy and develop off-flavors if stored for too long. Before using the stored eggplant, give it a quick rinse with cold water to remove any excess salt, and then pat it dry with paper towels to remove excess moisture. Keep in mind that the texture and flavor of the eggplant may change slightly after refrigeration, so it’s best to use it in cooked dishes where the texture won’t be a concern, such as stews, soups, or braises.
