Kohlrabi, also known as knol-khol or German Turnip, is a stout, round, tuberous vegetable in the Brassica family. It’s native to Europe and the temperate climates worldwide for its succulent round shaped modified stem as well for its turnip-flavored top greens. Some of the popular cultivars grown worldwide are white Vienna, white Danube, purple Vienna, and grand duke.
It requires well-drained fertile soil and average sunlight to thrive. Its edible stem attains maturity and ready for harvest in 55-60 days after sowing.
The approximate weight is 150 g. Unlike turnip which is a root vegetable, kohlrabi being a stem vegetable has less propensity to cracking and has a good standing ability for up to 30 days even after maturity.

Selection and storage
The best time to enjoy these potatoes is during winter from November to March when they are most plentiful.
Overmaturation and exposure to intense sunlight reduces their culinary quality. Look for fresh kohlrabies that can crunch on your bite and have a tasty flavor.
The store will have tubers of medium size, with good texture, sans cracks or cuts. If a hand feels too light when carrying tubers, or if it has an excessively woody texture, avoid buying them as they display signs of overmaturation which spells unappetizing.
This tuber also has good keeping qualities, so you can place them at room temperature for three to five days without refrigerating in case you’ll be storing them for some more time too.
Preparation and serving methods
Kohlrabi should be washed thoroughly in clean running water and swished in saline water for about 10-15 minutes to remove any surface soil, dirt, and any insecticide/fungicide residues.
Just before cooking, you can remove any leaves and trim the stem ends. Peel the skin using a paring knife. Kohlrabi is typically mixed with other vegetables or greens in recipes like empanadas or stewed with onion, garlic, and tomato.
Safety profile
Kohlrabi may unexpectedly contain plant-based compounds that can cause swelling in the thyroid gland and should be avoided in individuals with thyroid dysfunction. However, a healthy person can eat them liberally (without risk).
