Food is an edible item that can be used to treat the player's Hunger throughout the game.
You can eat three Fireweed plants to gain a bar of hunger. Only the Raspberries are edible, the Red Baneberries are poisonous.
To create food, you have to first either shoot an animal or trap it. Doing so will make the animal drop a corresponding size and amount of raw meat. To make the meat edible, you have to start a fire at the fire pit near your cabin. Drop the raw meat from your inventory onto the fire and it will produce cooked game. You can eat this cooked game or store it in your inventory or cabin.
