Set your smoker to a low temperature, around 180-200°F (82-93°C). I usually use the lowest temperature of my smoker because the low temperature gives you better control over the smoking process, ensuring a high-quality end product.
Place desired salt in a splatter screen or disposable aluminum 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.
Carefully transfer the splatter screen or aluminum foil pan to the preheated smoker.
Close your smoker and smoke for at least 3 hours or more, stirring occasionally until the salt has reached the desired potency. The time will vary greatly depending on individual preference and smoking temperature.
Let the smoked salt cool down before transferring it to an airtight container.
Store in a cool, dry place.
