Salt: the mineral, the work and the foods it makes
Salt seasons a meal, shapes fermentation and preserves food. Its history follows the people who mine, harvest, trade and transform it, and the choices hidden inside an ordinary packet.
Traditional method
Alburquerque Asin Tibuok
asin tibuok · whole salt
Asin tibuok is a Boholano salt-making craft that turns seawater-soaked coconut husks into a salt-rich ash, brine and formed sea salt in specialized clay pots. This record follows one published account of the community process; it is not a validated household formula.
The documented craft
This preparation belongs to the Boholano salt-making practice of Alburquerque. A provincial profile describes its historical trade within Bohol and the current safeguarding work led with the local salt-making community. The 2025 UNESCO inscription identifies the practice as urgently needing safeguarding. These records concern a community-held craft, not a generic ash-salt recipe.
The provincial account describes a sequence from mature coconut husks and seawater to salt-rich ash, concentrated brine and salt formed in ku’n clay pots. It names the materials, tools and some intervals but supplies no quantities, salinity, temperatures, yield or finished-product testing. This page records that evidence without turning it into validated home-production directions.
Published process sequence
The Bohol Provincial Planning and Development Office account lists the process in order: gather and dry mature coconut husks; soak them in open saltwater pits for at least three months; chop and dry them for days; burn them for days; collect the salt-rich gasang ash; filter seawater through it in a sag-sag to make tasik brine; prepare ku’n clay pots; and evaporate tasik in those pots over controlled fires on a laga-an stove for many hours. The pots cool overnight before soot is removed. The source gives no numeric fire temperature or quantitative endpoint.
This is a description of the documented Alburquerque craft. It does not establish that generic coconut ash, seawater, or a home-built filter and stove will produce food-grade salt. The inspected sources do not report a finished-product composition or process validation.

Risks and precautions
This source describes a community craft, not a validated household salt-making process. Food-grade status and finished-salt composition are not established here.
- Gather husks from mature coconuts and dry them.
- Soak the dried husks in open saltwater pits for at least three months.
- Remove the soaked husks and chop them into smaller pieces.
- Sun-dry or air-dry the pieces in the kamalig for several days.
- Pile and burn the dried husks in the kamalig over several days.
- Collect the hardened, salt-rich ash called gasang.
- Place the gasang in a funnel-shaped sag-sag filter and pour seawater through it to produce concentrated brine called tasik.
- Prepare the specialized clay pots called ku’n to hold the tasik.
- Set the ku’n on the long laga-an stove and keep filling them with tasik as water evaporates over controlled fires for many hours.
- When the prolonged heating exposes the salt through fractured pottery, leave the pots to cool overnight, then remove soot to reveal the pottery’s reddish surface.
