Instead of butchering each animal every time you killed some to save meat from it, let us hang skinned and cleaned carcasses of animal on special trolley that can be built in cellar and store a lot of carcasses. With that way carcass should never decay, and you can just cut as much meat as you need for cook.
To be honest I was inspired by orca/cachalot chunks, it's so convenient that they can be stored as in-game object without need of instant butcher.
inb4 understand that fraction bois kills hundreds of animals every day and this solves nothing for them, it's rather convenient for normal players.
