Introduction to Kohlrabi
Kohlrabi, known scientifically as Brassica oleracea var. gongylodes, is a cool-season crop that belongs to the Brassica family, which also includes cabbage, broccoli, and cauliflower. Its name, derived from the German words “kohl” meaning cabbage and “rabi” meaning turnip, aptly describes its taste and appearance, which is often likened to a cross between a cabbage and a turnip. The vegetable is characterized by its bulbous stem and leaves, making it a visually appealing addition to any garden or meal.
Composition of Kohlrabi
To understand what parts of kohlrabi are edible, it’s essential to break down its composition. The kohlrabi plant consists of:
- Bulb: The bulbous part of the kohlrabi, which grows above the ground, is the most commonly consumed part. It has a thick, fibrous skin that can range in color from pale green to purple, depending on the variety. The flesh inside is crunchy and has a mild, sweet flavor.
- Leaves: The leaves of the kohlrabi plant are edible and can be used in salads or cooked like spinach.
- Stems: While the main bulb is the centerpiece of kohlrabi dishes, the stems can also be eaten and are often used in soups or stews for added flavor.
Nutritional Benefits
Before diving into the edible parts, it’s worth noting the nutritional benefits of kohlrabi. This vegetable is low in calories and rich in fiber, making it an excellent addition to a weight management diet. It is also packed with vitamins C and K, and contains a significant amount of potassium, which can help lower blood pressure. The antioxidant properties of kohlrabi, stemming from its content of glucosinolates, contribute to its potential health benefits, including reducing the risk of chronic diseases.
Preparing Kohlrabi for Consumption
The preparation of kohlrabi can vary greatly depending on the desired outcome, from raw salads to cooked dishes. Understanding how to prepare each edible part is crucial for bringing out their flavors and textures.
Peeling and Cutting
The bulb of the kohlrabi needs to be peeled before consumption to remove its tough, fibrous skin. Peeling can be done using a vegetable peeler or a knife, taking care to remove as little of the flesh as possible. Once peeled, the bulb can be cut into various forms, such as slices, cubes, or julienne strips, depending on the recipe.
Cooking Methods
Kohlrabi can be cooked in several ways, each method highlighting its unique characteristics:
– Boiling and Steaming: These methods help retain the crunch and flavor of kohlrabi, making it a great side dish.
– Roasting: Roasting brings out the natural sweetness in kohlrabi, adding a depth of flavor that complements a variety of dishes.
– Sautéing: Quickly sautéing kohlrabi in a pan with some oil and seasonings can make for a tasty and healthy snack or side dish.
Using Kohlrabi Leaves and Stems
The leaves and stems of the kohlrabi plant, while often overlooked, can add freshness and flavor to dishes. The leaves can be:
– Added to salads for a peppery flavor similar to arugula.
