What to do with sunchokes?

So, we're signed up with an organic grocery delivery service (Pioneer Organics), and get to tweak our order online before it's delivered. We noticed local sunchokes available, and decided to try some. (Sunchokes are also called Jerusalem Artichokes, some good info on Wikipedia as usual).

The only problem was what do you do with them? I'd never cooked them before, so I headed off to Foodtv.com to look for recipes. It looks like there are basically 3 options:

• Mash them like potatoes
• Bake them (a la gratin)
• Make soup

We went for the last option this time around, and this recipe turned out very nicely. The sunchokes have a slightly sweet taste, with an earthy tone - quite like artichokes.
