oh starvation is a mod that aims to add a bit of difficulty to the game by changing the feeding process. As you may know, by default players can even eat raw meat for sustenance. With this mod installed, after collecting the food, we will have to process it to consume it.
For example, if we kill an animal to obtain its meat, we cannot eat it raw, nor put it in the oven, we must first hang, skin the animal and then cook it, as we can see in the picture below. The same will happen with vegetables, we will not be able to eat them directly, but we will have to wash them first.
