Devs: Why can oil not be made from boiling fat?

[scuseme]

Please consider adding boiling/ heating animal fat to make oil as an update.

Thank you!

I agree,there is a mod More Food, that implemeted the recipe, but I would like to see that in the official version.

That would make lard but it could be used in cooking like oil.

It just seems weird (and a pain in the ass) that the only way to make oil is from coconuts. Animal fat oil has been used since the dawn of time for lighting, heating and cooking. It makes sense (and I think is very realistic) that it should be able to be used that way in the game...

You can use fat to make candles, and many cooking recipes can use either oil or fat.

In-game, oil is treated as a liquid, while fat is treated as a solid, so switching between them (e.g., melting and re-solidifying) might be hard to code. Also, in general English usage, animal fats are not considered oil, even when refined and melted into liquid form, so from a conceptual standpoint it would be a bit odd to be able to interconvert them.

True but lard is technically only a semi-solid at room temp, but in tropic temps it would likely act like a liquid as rendering the fat into lard ruptures the fat cells themselves so it becomes much more "oil-like" at least in game terms... and it is a one way street, once you "render" the lipids out of the fat cells there is no putting them back in so pig fat + cooking pot + fire + time = lard & cracklings which would pretty much act exactly like oil and bad food/bait after that point.

Also just gonna leave this here in case people wanted to know more about the subject... or you could read the extensive animal parts post section of the Fauna thread if you really want to know this kind of stuff

Improving Animal Products (Updated Version)...

FATS & OILS

Rendering: Rendering is a process that converts waste animal tissue into stable, usable materials, most often this is used to refer to animal fats and oils. The process is usually to slowly cook the fats out of organs or unusable parts of the animal thus "rendering fat." The terms for types of rendered fats/oil depend mostly on the type of animal you are doing it to. This includes all the tough bits of meat and connective tissue to difficult to cook or eat, the stuff scraped off of the inside of leather when fleshing it, and any organs you would rather render than cook, eat, or feed to another animal and instead cook down into rendered fat and cracklings/greaves.

Lard: The rendered fat/oil from boars and pigs. This would be the major benefit of raising boars into pigs (domesticated boars will actually naturally lose their tusks if they don't need them and pigs will grow them if released into the wild, it is pretty cool) Having fat and lazy pigs over the survivalist boars would give much more fat and thus fatty meats like fatback & pork belly, which can be sliced into bacon proper... or the fattier meat could be rendered into lard.

Tallow: Rendered organ fat from bovids, bears, and most carnivores (like dogs and cats). Tallow is functionally very similar to lard but is typically more nutrient dense and of course is not typically free floating lipids like lard and must be rendered from suet or other fatty organs. Suet refers specifically to the abundant fat found on and around the livers of bovids, sheep, and goats.

Schmaltz: The rendered fat of domestic fowl. This is often used in lieu of lard by religious groups that do not eat pork. The name schmaltz is actually Yiddish because of this close tie. This is often goose, turkey, or chicken fat but it can be made from any fatty fowl.

Cracklings/Greaves: These are the tough bits left over from rendering fat into lard, tallow, or schmaltz and are typically connective tissue and coated in fat & oil. This makes them great for dog/hog feed or treats or for use as bait.

Ghee/Clarified butter: Rendering butter down into a far more concentrated oil/fat this version of animal oil/fat would not give cracklings like other animal oil sources, though it would require a great deal of butter and time to make.

Marrow: Most bone marrow is entirely or almost entirely made from thick fats. These fats are what make a bone broth favored and not just water with bones it it. If you break the bones and scrap the fat out rather than relying on slow boiling the fat out it can be used like butter or other fatty spreads or clarified/rendered like other fats or oils.

Fish Liver Oil: Made unsurprisingly from the fatty livers of fish rendered in a cooking pot and strained through a piece of cloth. This turns fish livers into fish oil which is often used as a folk remedy for almost everything (often called cod liver oil) This oil can be used to cook with (like other cooking oils) or for burning in oil lamps. The main drawback of fish liver oil is that it smells incredibly fishy, sort of like a terribly scented candle. Some fish, like oilfish would give MUCH more oil from cooking down the entire oily fish into fish oil as an alternative to eating them and possibly getting the poops.

Shark Liver Oil: Shark liver oil would also fit here and would effectively mimic fish oils. Both are used in cooking and both are rendered in basically the same way.
