Skordalia (Potato Garlic Spread)

I never would have thought of making a dip out of potatoes, but this Greek spread is delicious and VERY garlicky. I use skordalia as a substitute for hummus. It can be served with almost anything but most traditionally beer battered fish, eggplant or zucchini. My favorite is to use it in a pita sandwich with veggies and meat or falafel (spl?). It is also perfect to bring to a potluck with bread to dip.
