Such as in your inventory, if you cooked your meat well, it will just be called "Cooked Meat." If done bad, then it will be called "Burnt meat, ruined meat, etc."
If you are really on the edge of survival without anything to set up a fire, you would have to eat your deadly creation. It would cost you though, such as if you eat your burned meat, a message will appear saying "You have eaten burned meat and fell ill. Charisma -3" Or something on the lines of that. Or even better: "You have eaten burned meat and felt nauseous, you throw up on your t-shirt and reek of a hideous scent. Charisma -4" For me, I think it would make hardcoe more fun. Having that type of consequence out in the wastes would be nice.
