Place your choice of salt on the splatter screen or foil tray. I used two types of salt: flaky and kosher.
Carefully spread the salt in a thin layer to ensure even smoke distribution and penetration.
Load the pellet tube with wood chips, then light it. Put in a clean grill or smoker (without lighting them), carefully transfer the salt inside, and close the lid. Stir occasionally for better smoke penetration.
For a milder smokiness, 2-4 hours will be enough. If you want a stronger flavor, smoke salt for 8-12 hours, and for that intense BBQ vibe, up to 24 hours will do you well.
Let the smoked salt cool if needed, then transfer it to an airtight container and store it in a cool, dry place.
