Preservation

Various ways to preserve food past its normal expiration date.

• Potted food
• Canned food

One way to preserve food is to pot it, a process in which the food is isolated in liquid fat and kept inside a pot.

The first step for this process is to knap a small pot from clay and fire it in a Pit Kiln.

Then, craft the fired small pot with Rendered Fat, Saltpeter, and up to six meats or vegetables that you wish to pot. Pots can hold only one type of food at a time.

If you have the Firmalife addon installed, you can also use Butter in place of the Rendered Fat.

Other forms of preservation are useful, but the ultimate form of preservation is canning. This process involves sealing food in an airtight container, so that no microbes can reach it, and then heating the container to kill all of the microbes that are already on the food.

The raw material that cans are made from is called Tinplate. It is made by welding a Tin Sheet to a Steel Double Sheet.

A Wrought Iron Double Sheet can be used instead of a Steel one, at reduced efficiency.

Once welded, Tinplate can then be forged into an empty Tin Can.

A heated tin can can be crafted with a Hammer, Flux, and up to 6 Cannable Foods to create a Sealed Tin Can. Only one type of food may be kept in a given can.

The can is then heated to kill the microbes inside, resulting in a Sterilized Tin Can. The food inside the can will last forever, until the can is opened, at which point its expiration date will start anew.

To open a can, craft it with a Can Opener. This recipe will output the food that was in the can.

Can openers are crafted using one Brass Mechanisms, two Rods made of any tool metal, and two Circle Blades.

Circle blades are forged from metal ingots.

If you don't have a Can Opener on you, you can also open a can with a Hammer. This results in a Dirty Dented Tin Can.

This can must be cleaned first, like normal Dirty Tin Can. Then it can be repaired on an Anvil.

Since cans are sterilized by heating, they can sometimes gain food traits, such as Charcoal Grilled or Wood Grilled. These traits have no effect, since sterilized cans don't expire, but can be removed for cosmetic or stacking purposes by placing the can in your crafting grid.
