From 1915:
I suppose every one knows how to make potato chips, yet the recipe may be of use to some of the new cooks. And there are always a lot of them, thanks to little Dan Cupid and Mere Man’s propensity for a good dinner. This is the way I make potato chips.
Peel and slice some good potatoes and lay them in cold water for an hour. Dry by laying-them on a dry towel and pressing them with another. Fry in salted lard, quickly, to a delicate brown. Take out as soon as they are done. Shake briskly in a hot colander to free them from the fat and serve at once in a hot dish lined with a napkin.
