Candlenuts are one of those hidden treasures of nature that not many people talk about—yet they’ve been used for centuries in traditional foods, medicines, and even crafts. If you’re someone who loves discovering unique superfoods from around the world, candlenuts definitely deserve a spot on your radar.
These rich, oily nuts are popular in Southeast Asian cuisines—especially in Indonesia, Malaysia, and the Pacific Islands—where they are used not just to enhance flavor but also for their amazing health benefits. Known scientifically as Aleurites moluccanus, candlenuts have a fascinating history and a strong cultural presence. Let’s dive deep into everything you need to know about candlenuts—from what they are to how they influence your health.
What Are Candlenuts?
Candlenuts come from the candleberry tree (also called the kukui nut tree), which grows in tropical regions. The name “candlenut” comes from their traditional use as a natural source of light—they burn like candles due to their extremely high oil content.
They look somewhat like macadamia nuts: round, creamy-white inside, and covered in a tough, brown shell. However, unlike macadamia nuts, candlenuts must be cooked before eating. Raw candlenuts are toxic and can cause serious digestive distress.
Interesting facts about candlenuts:
- They are the state tree of Hawaii, where they are known as “kukui”.
- Historically used for making torches, candles, and varnish.
- A staple thickening ingredient in Southeast Asian dishes like curries and sambal.
Not only do candlenuts elevate food flavor and texture, but they are also packed with nutrients that support overall wellness.
