We found this recipe at the back of an old drawer here in my husband’s home where the family have lived for nine generations. No one remembers having tried this recipe before. Bitter almonds are very difficult to find. They are occasionally to be found in Oriental shops. You can substitute sweet almonds and add a few drops of bitter almond essence (plain almond essence will not do), but again this is hard to obtain. You will probably have to settle for using ordinary sweet almonds and the result will be very good, if not totally authentic.
