Yes Ingvild, I learnt this recipe from my Dutch friends as well. It's really delicious, and you can also mash in some celeriac to go with it.

I have kohlrabi growing. Lots of leaves which are delicious cooked like spinach. Unfortunately there is no swelling at the base yet. How long should it take to start to see something. I have problem with onions not swelling also. Is this the same reason?

Hi Amanda. When i lived in temperate Sydney, the kohlrabi was a lot less bulbous as well. Perhaps it is the region you live. Kohlrabi, and most of the family, grow slower in the cooler regions. I'm no scientist, but I've noticed this. Maybe it grows too quickly?. The same would apply to onions I think. I tried growing onions in the south of India a couple of years ago. The heat just turned them into spring onions, almost no bulb at all. Just a theory. Maybe you could try in the shady? It might work.
