Ways to reduce bitterness in turnips

I pride myself in eating anything, however, turnips may soon be added to a very short list of things that I don't care for (Brussels Sprouts) if I don't find a way to eradicate that bitter flavor they impart. I recently roasted a medley of root vegetables and the bitterness in the turnips stuck out like a sore thumb. I love my root veggies like parsnips and rutabaga, but those darned turnips ruin the party every time.

Suggestions?

ETA: Researching suggested soaking in dairy and/or selecting the freshest/youngest turnips. I think I recall a Keller recipe being adamant about the size of the turnips.
