Cromniomancy is divination by onions.
Cromniomancy was usually
done by inscribing “yes” or “no” on onions, then planting and asking
your question of them to see which one would sprout first. That would be
your answer. If it was a question of suitors, one would inscribe the
name of possible lovers, one to each onion, then whichever one sprouted
first was your true intended.
