Boil in their skins three good-sized potatoes, peel them and slice
them, then put them into a salad bowl, and pour over them one-half a
glass of white wine. Do this about two or three hours before they are
wanted, so the potatoes will have time thoroughly to absorb the wine.
From time to time mix them with a fork and spoon to let the wine
permeate. A few minutes before the meal make a good French salad
dressing, add some pickled peppers cut up, some capers, and some
chopped-up parsley, pour on the French dressing, mix up well, and
serve.
