Most foods have a perish time, meaning they will spoil over time, losing nutritional value, and eventually turn into rot. To combat this, there are certain preservation methods to keep your food supply fresh, like special storage containers and cellars.

[[Rot|Rotten food]] inside a container such as a bowl, crock or pot can be removed by dropping it into water. After a few seconds, the rot will float to the surface and separate from the container. Sealed crocks with rotten food need to be first unsealed, by getting one food portion with a bowl.

=== Shelf Life===
==Shelf Life==
Every kind of object has a different "perish time" which is composed of their “freshness time”, which is the time it takes for a fresh item to start spoiling; and their “spoilage time”, which is the time it takes for the item to turn into rot.

When combining stacks of food items, their average overall perish time will become the new perish time for both items.

===Cooked Meals===
For cooked items, their new shelf life depends on the freshness of the ingredients. Fresher ingredients mean much longer preservation time. If you cook with a partially spoiled ingredient the new meal will start spoiled.

Almost all types of food items can be stored in the form of cooked meals, but it’s not always practical to do so. For this, there’s special food processing methods that increase their lifespan significantly. Due to the different components in foods, there are various processes to preserve each type or category of food.

=== Jam (Preserving Berries) ===  
 
=== Jam ===  
Making jam requires a cooking pot, a bucket, honey, and berries. By using a cooking pot, add a minimum of two berries and two units of honey to make jam. For the longest shelf life, jam should be stored in a sealed crock.

=== Salt Curing (Preserving Meats) ===
=== Salt curing ===
Curing meats requires a barrel, salt and the raw meat to preserve. Each unit of meat requires two units of salt, i.e. 32 meat = 64 salt. After adding the appropriate ingredients into the input slot of the barrel, the GUI will state the process yield. At this point the barrel must be sealed for 480 hours to complete the curing process.

=== Pickling (Preserving Vegetables) ===
=== Pickling ===
Pickling vegetables requires a barrel, a bucket, salt, water, and the vegetables to preserve. Water and salt are mixed in the barrel to make brine before adding the vegetables. Otherwise, the process of pickling is very similar to salt curing. Each vegetable or legume uses one unit of brine and the barrel must remain sealed for 336 hours. Once the food items are pickled or salt preserved, they can be stored in any stationary container, though storage vessels are best.

=== [[Cheese]] ===
Milk can be turned into cheese by processing it in several steps with pickled vegetables and salt in a barrel. See the cheesemaking section for more details.

To negate the impact of a warm climate, build a cellar. Cellars have a fixed temperature of 5°C or colder if the ambient temperature is lower, meaning you will only profit from a cellar if the outside temperature is higher than 8°C in the first place.

=== Recommendations ===
=== Recommendations ===
* Build the walls from soil, ceramic, or stone materials and keep door/trapdoor count low. It’s best to not use any doors/trapdoors, and instead use dirt or hay as full-block fillers. The less light inviting openings the cellar has, the better - additionally, doors do not count as a soil or stone block and thus lower the efficiency, even if they do not let in sunlight.

== Removing the Rot from Bowls, Pots and Crocks ==
If food has rotten inside a food container such as a bowl, pot, or crock, you just need to throw it in water and, after a few seconds, the rot will float out of the container. For sealed crocks, you might need to unseal it first (getting a food portion with a bowl).
