Years ago, when I was in college, one of my roommates pulled a weird alien looking ball out of the fridge and proceeded to matter of factly peel and slice it to eat. She replied to our questioning in a voice that indicated it was obvious, she was eating kohlrabi.
Turns out it is delicious. You can cook the leaves like any other green. My favorite way to eat the bulb is to peel and slice it and then serve it raw with a bit of sea salt sprinkled on top.
This is also good for you, just in case the excellent taste (which I can’t adequately describe) isn’t enough incentive to try it out for yourself. Raw it’s an especially good source of vitamin C, potassium, and (this surprised me) it is also a source for Omega 3 and 6 fatty acids 🙂 .
