When peaches are in season, have in a convenient place an old basket or something of the sort, in which all the peach stones can be saved; they are too useful to be thrown away. Then have them carefully cracked, so as to extract the kernels whole if possible. Spread them out on a dish for one day. Then put them into a box or jar, and keep them to use as bitter almonds; for which they are an excellent substitute in flavouring custards, creams and sakes. Plum stones are worth saving in the same manner.
