Once you have access to cooking oil, (most commonly for me is plant bladders(1), but cotton(1)/canola(4) seeds are also available once you can farm) and flour, then biscuits are insanely good. (24 at 8 portions = 192 nutrition. Also makes you healthier.) for 2 flour and one cooking oil. Even if you can’t farm, 2 buckwheat or 2 cooked acorn meal yields 10 flour, and 1 plant bladder yields 2 cooking oil.
If you are using the survivor mess kit (10 volume, 2 boiling, 1 containing, 1 chemical making, 3 food cooking quality) you can also convert cooking oil into lamp oil, which the survivor mess kit uses. I believe you can also start a fire nearby and still use the survivor mess kit without the oil too, but don’t quote me on that. You need 4 fabrication to attempt to make a lamp oil cooker, from a oil lamp (created at 3 fabrication and it requires either a glass flask, jar, or bottle, a tin/aluminum can (or an empty canister or a clay teapot/jug), a rag, and a scrap metal), a pilot light (disassemble a used up or spare lighter), 50 duct tape, and 3 scrap metals. You then combine the lamp oil cooker with some kind of pot, and this will make the survivor mess kit. You’ll need a least a rock to create the oil lamp, but that shouldn’t be too hard.
The hardest part about this recipe may very well be the duct tape.
If you can farm and you have them, farming beans and something that can give either sugar, or sugar beet syrup (sugar beet syrup doesn’t spoil in my current experimental game) can be combined with your smoked meat (or later on, if you want to get away from that, canned meat is good if you have jars, and canning meat can be made faster in my current experimental, so it’s slightly slower to can meat than it is to smoke it, but not by much when you factor not having to deal with charcoal in.) to create baked beans. Baked beans gives you 4 potions of 44 nutritional food which equates too 176 nutrition. But more importantly, the biscuit covers the wheat food group and the baked beans covers the flesh and plant matter food group.
This equals a healthier diet in-game, which I don’t know if it has any effects on your health, but it might matter in the future once the devs or a good modder implements a proper nutritional system, so this is a good habit to get into eventually. The biscuit itself is healthy for you though. 10 units of flour = 1 volume, 2 units of cooking oil = 1 volume (but it needs to be kept in a container, which why doesn’t flour need to be kept in a container? Gives us a good use for those plastic bags.).
Lastly, plant bladders can be easily acquired by killing funagloids, or triffids. Fungaliods seem to be way more common for me though, for some reason, but whatevz. Just make sure you are well covered.
