I was very surprised to find kohlrabi in the Dutch supermarket after four years of living in the Netherlands. I even had to double check with my mom if that's the vegetable I knew from Taiwan (I sent her a picture). Turns out, it is!
I immediately asked my mom to send me the Su family secret recipe for making Taiwanese pickled kohlrabi.
I am showing it here, so of course it is no longer secret now, haha.
