I won't recommend doing such a thing. You can convert Chilled Meat to Raw Meat by processing it, but that's very inefficient. Firstly, it's tough to explore Dragonspine, and you'll have around 16 locations where you can get Chilled Meat. It's not worth the effort to convert it to Raw Meat, which you can easily farm in the overworld or even buy from shops. I recommend you have some Chilled Meat in your inventory but don't convert it.
