History: Alaea salt is a traditional Hawaiian sea salt distinguished by its rust-red hue. The alluring color results from mixing unrefined sea salt with ‘alaea, a naturally occurring volcanic clay rich in iron oxide.

Hawaiian salt is traditionally harvested by hand from natural tide pools. The island of Kaua’i, especially the Hanapēpē Salt Ponds, remains a historically significant location for salt harvesting and is a protected cultural area.

The arrival of Western explorers and missionaries in the 18th and 19th centuries changed Hawai’i’s traditional salt practices. By the mid-1800s, alaea salt became a valuable export, especially to the Pacific Northwest, where it was used to cure salmon.

Commercialization led to attempts to mass-produce alaea salt, often without cultural protocols or genuine local sourcing. Many products labeled “Hawaiian Red Salt” are not produced in Hawai’i and use artificial colorants or imported clay instead of native ‘alaea.

Interesting Facts: In Hawaiian, the word for salt, “pa’akai,” literally means “solid sea”.

‘Alaea clay contains over 80 trace minerals.

In Hawaiian tradition, salt ponds were considered sacred (kapu) and entry was forbidden to outsiders.

Uses: Alaea salt takes longer to dissolve than refined salts and is best used for finishing dishes.

Selection & Storage: True alaea salt should have visible variation in hue and smell, whether briny or mineral-rich. It should not contain any dyes or anticaking agents.

Genuine Hawaiian alaea salt is protected by cultural designation. Local producers aim to preserve traditional methods. If possible, try to find salt that was produced in Hawai’i.

Taste Rating: ★☆☆☆☆

Alaea salt is milder than table salt with earthy undertones.
