It seems simple enough however I question if one way is better than others. My mother insists they must be boiled with their skin on to retain flavor. I have done it that way but have also peeled and cut into cubes before boiling for potato salad. I happened to watch Tyler's Ultimate yesterday and he traveled to Ireland to learn how to make a charming dish colcannon. The lady who cooked it insisted the potatoes be steamed to retain nutrients and flavor. So I decided to make a warm potato salad for dinner just to try out this theory. I steamed them in a double boiler and they were indeed tasty and I patted myself on the back for "retaining some nutrients." Any truth to this?
