The key for me is to jazz them up somehow. I really dig them in a salad with dried cranberries and green olives and some (not as good for you) ranch dressing. I kind of hate them mashed with potatoes. I figure if you are going to eat turnips, you should just eat them. I don't like messing with a culinary masterpiece like mashed potatoes.
My latest attempt at getting the family to enjoy turnips is to turn them into chips. You can fry them, but I figure that defeats the purpose of eating a healthy veggie, right? So this time around I baked them. ...and because I want you to keep reading, I'm going to show you the finished product first. Aren't they pretty?
Moving on, the first thing you do is figure out what a turnip is. That large round ugly looking thing in front is a wax turnip or rutabaga and the white veggies in back are your garden variety turnip. You might be tempted to go for the biggest ones you can find, but the smaller ones are actually more flavorful. However, they take more time to peel, so I usually take a compromise and go for some medium sized like these.
