A maiden gathers a handful of nuts and names each for a potential suitor. On Halloween Eve she places all the nuts on a grate over the fire. If the nut burns true and does not move, the suitor will be faithful. If the nut moves or pops, the prospective lover will be unfaithful.
A maiden gathers two nuts, one for herself and one for her suitor. On Halloween Eve she places them on a grate over the fire. If the nuts burn well together, then a long marriage and happiness is foretold. If however, one nut darts sideways, the person the nut represents will stray and the other person is advised to seek a different mate.
