Potato Fricassee
Put in a saucepan 1 generous tablespoon of butter and 1 cup of milk; when hot add some cold potatoes cut in dice, season with pepper, salt, and a few drops of onion juice. Let them get thoroughly hot, then add the beaten yolks of 2 eggs, stir constantly until thick. Great care must be taken not to let it cook too long or the sauce will curdle. Add a little chopped parsley before serving.
