1--I think kohlrabi is really good raw, especially if they are not too big. They are good as strips with veggie dips and in salads. My kids liked them this way even when they thought they didn't like vegetables very much. Some adults are surprised to learn what they are eating as well!

2--Cook them like turnips in a bit of water and then dress them up. They are good with a mild cream sauce (some people call it a white sauce--the basic flour and butter and milk sauce) like creamed potatoes or creamed turnips. Maybe spice up the cream sauce with dill or tabasco because they are fairly bland.

3--Make a beef or chicken soup and add them as one of the veggies--instead of carrots or potatoes is nice. I like them in a fairly beefy soup with onion and celery.

4. Hide them by blending them in with mashed potatoes. (I also do this with cauliflower.) It adds a nice flavor but is not obviously kohrabi. I cook the potatoes and kohlrabi or cauliflower together and mash them together. And dress it up with chives or parsley or whatever.

5. They really taste better when they are picked sort of small or medium sized. I think they get a little strong-tasting when they are bigger, but simmering them in milk may make them a bit milder if they are really strong.

Hope this helps out.
