candle nuts

Candle nuts (Aleurites moluccana), also known as candlenuts, kukui nuts, or lumbang, are the fruit kernels of a tropical tree native to Indonesia and Malaysia and widely cultivated throughout Southeast Asia and the Pacific islands. The nuts are cream-colored, roughly spherical, and enclosed in a hard, smooth shell. Raw nuts contain a purgative compound and must be roasted or blanched before consumption. The flavor profile is rich, buttery, and slightly bitter, with a subtle nutty character that intensifies with roasting. The high oil content (approximately 50-60%) historically made them valuable as a fuel source before the modern era—individual nuts were threaded on a rib and burned as candles in Southeast Asian households, hence the common English name.

Candle nuts are essential in Southeast Asian cuisines, particularly Indonesian, Malaysian, and Thai cooking. They are typically roasted and ground into a paste to serve as a thickening and enriching agent in curries, satay sauces, and coconut-based dishes such as rendang and opor ayam. The nuts provide body and richness without the grainy texture of other thickeners. They are also crushed and added to spice pastes (such as those for sambal) and used as a binding ingredient in dumpling fillings and meat preparations. In Hawaiian cuisine, roasted and salted kukui nuts are eaten as a snack or used as a garnish. The nuts should always be roasted before grinding to remove any raw toxins and to develop their characteristic flavor.
