Salt is a rare cooking resource in Windrose, mostly tied to the second biome and used for higher-tier meals that boost survival stats. It rarely appears in the wild, so most players end up choosing between fighting for it at sea or buying it from a faction merchant.
Quick answer: Buy Salt from the Provisioner in Tortuga (Undead Waters region) for 2 silver per unit, after reaching Brethren of the Coast reputation level 2.

What Salt does and where it sits
Salt is classified as a Rare resource and is listed in the Discovery menu as a cooking ingredient found in ship holds across the archipelago. It belongs to the second biome's progression tier, which is why early-game players struggle to find it before reaching the Foothills and Undead Waters areas.
Its main purpose is cooking. Several mid- and late-game recipes call for Salt to produce meals with stronger stat buffs, which matters more once enemies and biomes get tougher.
Method 1: Buy Salt from the Tortuga Provisioner
This is the most consistent way to stockpile Salt. Tortuga is located in the Undead Waters region, and a vendor labeled Provisioner inside one of the buildings sells Salt directly for silver.
Step 1: Sail to Tortuga in the Undead Waters region. If you have not unlocked the area yet, follow the main questline. The quest "Underground Network" in your Journal points you toward the exact location.

Step 2: Reach Brethren of the Coast reputation level 2. The Provisioner will not sell Salt to you below this threshold, so any reputation grind with that faction needs to be cleared first.
Step 3: Enter the Provisioner's building in Tortuga and interact with the NPC to open the merchant menu. Salt appears in the goods list alongside other trade items like Coffee.

Step 4: Select Salt and buy as many units as you need at 2 silver per unit. Confirm the purchase by clicking Buy until your stack is large enough for your cooking plans.
Method 2: Loot Salt from ships and sea caches
Salt can drop from enemy vessels you sink in the archipelago, including Blackbeard's Transport and Blackbeard's Raider class ships. The drop is not guaranteed, and the rate is low, so this method is unreliable as a primary farm.
Drifting sea caches floating in the water can also contain Salt occasionally. These are passive pickups, so it is worth scooping any you pass while sailing between objectives, but do not plan a run around them.

Method comparison
| Method | Source | Requirements | Reliability |
|---|---|---|---|
| Vendor purchase | Provisioner in Tortuga | Brethren of the Coast rep 2, 2 silver per unit | High - guaranteed stock |
| Ship loot | Sunk enemy ships in the archipelago | Combat-capable ship | Low - rare random drop |
| Sea caches | Drifting caches in open water | None | Low - opportunistic |
Why the vendor route is faster
Grinding ship drops takes far longer than running reputation tasks for the Brethren of the Coast. Each successful sinking has only a small chance to yield Salt, and you still need to repair, restock ammo, and sail back. Buying from the Provisioner converts silver directly into Salt at a fixed rate, which scales much better when a recipe demands several units at once.
If you are short on silver, prioritize selling excess loot and completing faction-aligned objectives in the Undead Waters region. That builds Brethren reputation and your silver pool at the same time, which removes both gates blocking the purchase.

Common reasons the purchase fails
- Reputation with the Brethren of the Coast is below level 2. The Salt entry will be visible but locked.
- You do not have enough silver. Each unit costs 2 silver, so confirm your balance before opening the trade menu.
- You are speaking to the wrong NPC. Only the Provisioner inside Tortuga sells Salt; other merchants in the area handle different goods.
Once those conditions are met, Salt is effectively unlimited as long as you keep earning silver, which makes it the cleanest long-term solution for any cooking-heavy build in Windrose.
