Peel some medium-sized white potatoes, and slice them very thin. It is
better to have a potato slicer for these, if possible, as it cuts them
so quickly and perfectly. Wash the potatoes in one or two waters, then
cover with fresh water and lay a lump of ice on the top of them. Let
them stand an hour, if convenient, drain in a colander, wipe dry with a
towel, and fry in boiling fat--not too many at a time in the basket or
they will stick together, and will not brown. Have a quick fire, and fry
until brown and crisp, drain on paper, sprinkle with salt and serve.
