Similar to the Ice Box, the Salt Box can be used to store and preserve up to 9 stacks of FoodItems. The Salt Box slows the spoilage of food by four times, which is twice the efficiency of an ice box. However, it cannot contain Crock Pot dishes, cooked food, plantable items such as Seeds, and items that do not have a cooked form, such as Honey or Ice.
The Salt Box was introduced in the Salty Dog update.
Ironically, Jerky cannot be stored in a Salt Box, as salt is used to further preserve jerky in real life.
