The nuts, which are actually seeds, are encased in a soft, indehiscent fruit and are rich in oil. The term “kukui” translates to “enlightenment” in Hawaiian, reflecting the nut’s traditional use as a light source. By drying and polishing the nuts, the Hawaiians created candles that provided light, hence the common name “candlenut.”
Cultural and Historical Significance
The cultural significance of kukui nuts in Hawaii cannot be overstated. In ancient Hawaiian culture, the kukui tree was considered sacred, and its nuts were used in a variety of ceremonial and practical contexts. The oil extracted from kukui nuts was used for lighting, as a varnish, and even in traditional medicine. The nuts themselves were strung into leis, which were worn on special occasions as symbols of peace, prosperity, and good luck. Today, kukui nut leis remain a popular and meaningful accessory at Hawaiian weddings and other important events.
