What is kohlrabi skin and is it edible?
Kohlrabi skin refers to the outer layer of the kohlrabi plant, which is a cross between a cabbage and a turnip. The skin is typically a deep green or purple color, depending on the variety, and has a slightly tough and fibrous texture. For a long time, it was believed that kohlrabi skin was inedible and should be peeled before consumption. However, recent studies and culinary experiments have revealed that the skin is not only edible but also packed with nutrients and flavor.
The edibility of kohlrabi skin is attributed to its high content of vitamins, minerals, and antioxidants. In fact, the skin contains more fiber and antioxidants than the inner flesh, making it a nutritious and healthy addition to various dishes. When cooked, the skin becomes tender and can be easily incorporated into soups, stews, and sautéed dishes. Moreover, the skin can be pickled or fermented to create a crunchy and flavorful snack, adding texture and depth to salads and other recipes. With its unique flavor and nutritional profile, kohlrabi skin is an exciting ingredient for home cooks and professional chefs to explore.
How do I peel kohlrabi skin, and what are the benefits of doing so?
Peeling kohlrabi skin is a straightforward process that requires a vegetable peeler or a sharp knife. Start by trimming the stem and leaves, then place the kohlrabi on its side and peel the skin in a circular motion, applying gentle to moderate pressure. The benefits of peeling kohlrabi skin are mainly related to texture and flavor. Peeling can help remove any bitterness or astringency, resulting in a milder taste. Additionally, peeling can make the kohlrabi more palatable for people with sensitive digestive systems or dietary restrictions.
However, it’s essential to note that peeling kohlrabi skin also means losing some of the nutrients and fiber it contains. If you choose to peel, consider using the skin in other dishes or saving it for stocks and broths to minimize waste and maximize nutritional value. Alternatively, you can leave the skin on and cook the kohlrabi whole, allowing the heat to break down the cell walls and release the natural sweetness and flavor. Ultimately, whether to peel or not depends on personal preference and the desired outcome in your recipe, so feel free to experiment and find the best approach for your culinary needs.
