Hawaiian black salt (Hiwa Kai)

Hawaiian black salt, also known as Hiwa Kai or black lava salt, is a blend of sea salt and activated charcoal, often derived from Hawaiian coconut shells. The salt is harvested by evaporating seawater in above-ground pools that have formed naturally from lava flows, and the activated volcanic lava charcoal is added for its color and detoxifying properties.

It is rich in minerals and is known for its detoxifying effects, and as a digestive aid due to the activated charcoal it contains. The charcoal also contributes to the salt's striking color and unique flavor. Hawaiian black salt has a slightly hot, mineral flavor described as "volcanic" and is noted for its smoky taste and coarse texture, which makes it ideal for use as a finishing salt on a variety of dishes, including seafood, beef, chicken, and roasted vegetables.​​​
