What is kohlrabi technically, despite its culinary treatment?

Answer

A swollen stem treated as a root vegetable

Kohlrabi is botanically classified as a vegetable whose edible portion is technically a swollen stem that grows above the ground. Although its physical structure is a stem, its usage in the kitchen often mirrors that of root vegetables. This dual classification means that while it shares relationships with plants like cabbage and broccoli (being part of the Brassica family), its primary consumed part requires preparation methods often associated with root crops, even though it is physically distinct from them.
