Is there is secret of a perfect mash without the lumpy bits? No, unfortunately all electric tools seem to produce mashed potatoes with the gluey texture of wallpaper paste. The easiest way to a lump-free mash is some hard work with a potato masher, or to put the potatoes through a food mill. Additions such as olive oil, cream, butter and milk should be added while the potatoes are warm, along with seasonings of salt, pepper and nutmeg. Vigorous beating is what lightens the mash and at the final stage you could possibly use an electric beater set on a slow speed.
As an alternative to mashing, try riced potatoes, positively lump-free. A potato ricer, available from catering shops and good kitchenware departments, looks rather like a giant garlic press and crushes whole, cooked potatoes, extruding them in a light snow. Rice the potatoes directly into the serving bowl, adding butter and seasonings to the layers as you go. Riced potatoes can be reheated in their bowl, but stirring will sacrifice their lightness.
