Unable to render animal fat into oil

[Ary]

I have a fire, a cooking pot, and 5kg of animal fat but it says that I do not have the items required to create oil. My only thought is that it is ruined but that doesn't seem to matter with other ruined items w/ cooking like animal meat. Thanks!

You need to have one kilo of not-ruined animal fat in inventory. You can drop it all, pick up all the ruined animal fat then the not-ruined animal fat and that will get you past the "you're missing an ingredient" gate and the game, as it does the recipe, will take the first things you picked up, i.e. the ruined animal fat, and not touch the not-ruined stuff until that is all that is left.

This work-around works, for now, with things like maple syrup, pinnacle peaches, and probably corn (for recipe purposes). Presumably the same for ruined meat in a recipe. Oatmeal can still be made into porridge even if ruined so the game is not entirely consistent.

Good luck.
