Asin tibuok, a rare salt from the Filipino island of Bohol, is being revived thanks to chefs and TikTokers. The salt, which means "unbroken salt", is only produced on one small island. It was first recorded in the 17th Century by a Spanish missionary, describing the local practice of filtering seawater through the ashes of charred coconut husks and baking brine inside clay orbs. Despite its popularity, production of this salt has declined in recent years due to aging and lack of skill. Ethnoarchaeologist Andrea Yankowski first discovered the salt 20 years ago when she was researching the island. In 2025, Unesco recognised asin tibok as an Intangible Cultural Heritage in Need of Urgent Safeguarding. The process of making the salt, taking more than four and a half months to make, takes less than four generations to make.
