It tastes like broccoli stems. Some are more tender than others (just like with broccoli stems).

I usually slice into little julienned pieces and marinate it in salt and acid for it to wilt into some kind of modified cole slaw.

in addition to all the stuff people answered you can also cut it in about 1 cm thick slices, bread it and fry it in a pan like a schnitzel, which tastes awesome.

You can eat it cooked or raw, I personally prefer raw as a refreshing sweet snack.

It’s basically like a milder/sweeter turnip.

You eat it with your mouth, someone else will be along to tell you how to cook it
