A simple way to make food that last longer.
Reach level 18 to unlock the drying rag. Open “Crafting &Recipe” by pressing “P” and unlock “Cook Bench” to be able to craft the Drying Rack

So far you cant craft anything, you need to reach level 19 to unlock Pickled Meat and Salted Fish. Open “Crafting & Recipe” by pressing “P” and unlock “Pickling” to be able to craft it.

Once you got it unlocked press “E” on the drying rag and hover over the food to see which items you need to craft it.
