Traditionally Finnish pea soup is made with leftover ham, but URW recipe for pea soup asks, optionally, for 1 lb of raw meat.
It'd be... thematically appropriate, if we could use "left over meat" ... or in other words, preserved: salted, dried or smoked meat.
And even it'll be a pain to code, I'm suggesting to allow 1 cut of "preserved meat" to replace 1lb of raw meat in any recipe. While retaining the option to use raw meat/fat. Roleplay it as: "I got this seal fat and this dried elk meat, I think I'll simmer it into a stew."
