this post was inspired by @captcha in their quest to figure out what to do with their cannabis-infused coconut oil. this is a secret, forbidden technique! jk it was taught to me by a college friend who sold edibles. his method has never failed me. this method can be used for p much any type of fat extraction. once i extracted weed into heavy whipping cream to make ricotta for a weed lasanga. but you have to tweak the concentration if you use heavy cream bc its not pure fat.
before we start, you need some ingredients and equipment:
- 250 g of any fat (eq. to 2 sticks of butter, but you can use any cooking oil) USE UNSALTED BUTTER
- 7 g of ur finest bud
- 4-8 oz distilled water (you can use tap water, but i prefer water as soft as i can get for this)
- cookie tray
- aluminum foil
- oven/toaster oven
- oven thermometer
- saucepan
- mason jar
- something to stir with
- cheesecloth
- cup with opening thats wider than its body (mason jar's narrow opening wont work for separating the water and oil) i prefer a plastic cup bc you can squeeze it to more easily remove frozen oil

decarboxylating weed is very important bc it converts THCA (not psychoactive) to THC. but dont decarboxylate too long, THC eventually converts to CBN! CBN is psychoactive but not as fun as THC, just makes you sleepy. line cookie tray with aluminum foil, grind up/break apart ur 7 g of weed, and spread it out over the foil (spread it out dont bunch it up). make sure you preheat ur oven using an oven thermometer bc this process is very temperature sensitive. i go 250F(120C) for 25 minutes (maybe a bit less if ur cooking it a lot later) (THIS TIME AND TEMPERATURE WORKS BEAUTIFULLY, DONT TAKE IT FOR GRANTED).

once ur weed is decarbed it should look a bit more brown but still have a bit of green. transfer it to a mason jar along with 250 g of ur fat of choice. place this mason jar (NO LID) in a pot of boiling water (using this double boiler method is important so you keep ur oil and weed below the boiling point of water). stir this mixture for 30 minutes (it gets tiring but just do it so all the THC dissolves, if you need a short break make sure you use something heavy to secure ur jar in the water).
-
after stirring for 30 minutes, add 4-6 oz of distilled water and mix for another 10 minutes. the water extracts tannins and plant alkaloids from the oil (these chemicals have an unpleasant, bitter taste and this step removes a lot of them)
-
using a cheesecloth to strain out the weed chunks, transfer to the cup with a wide opening. rinse out the jar with a few oz of water and squeeze that cheesecloth, you dont want to miss out on any THC!

now pop that sucker in the freezer! butter freezes the fastest, but all oils will freeze in a freezer. oils also don't crystallize, so when theyre solid they all have a consistency similar to butter so theyre easy to manipulate. wait for the oil and butter layers to freeze and then just separate the frozen oil layer from the ice layer. it should be pretty easy, the frozen oil usually slides clean off.
now you have a beautiful cannabis-infused cooking oil thats cheaper and only takes an hour of work and an hour of waiting!
If you’ve got a digital candy thermometer and a digital meat thermometer (the kind you use for a bbq with a remote probe) you can clip em both on, set em both for the min and max temperatures and walk away.
One goes off when the temp gets too low and the other goes off when it gets too high so even with a cheap coil burner you can poke the heat up or down and do real long extractions while you read a book or something.
After talking to a friend who works with extracts it turns out they use basically a more tightly controlled version of this industrially where there’s automated stirrers and a feedback loop, etc.
thats smart as hell, thanks for the advice! that should work just as well as oven. youll have to tweak the oven temp anyways since consumer-grade ovens suck at keeping a constant temp
yeah i had to get up probably eight times in two hours but managed to cram half a qp into two pounds of oil.
had to clarify it twice but the result was very clean and strong.
oh wow, thats 4x more concentrated that my method. mine would prob make cookies at 100mg. ive done higher concentrations before for personal use but im gonna try ur concentration next time!
