Success!
My first attempt with blender, water and coconut oil turned into a gloopy mess that never separated. So it occurred me, if I'm making a coconut oil extract why do I need water? Well I don't. So here is my method:
Ingredients:
- 1/4 US cup (60 mL) coconut oil (Mine is "refined" but it probably doesn't matter if you use "unrefined")
- 1/4 US cup (60 mL) kava medium grind powder (I used KWK Borogu)
- A microwave-safe dish
- A kava strainer (I used one of the nice 70 micron nylon ones I got from Cactus Kava)
- A small Tupperware-or-equivalent container
- A meat thermometer
- A refrigerator (You can buy one from @Kapmcrunk if you don't have one)
Instructions:
- Place the coconut oil in the microwave-safe dish
- If the coconut oil is solid, heat in the microwave for about 15 seconds to melt it. It should be a clear-ish liquid with no unmelted white chunks.
- Mix the kava powder in with the coconut oil. Mix thouroughly. It should be more liquidy than solidy.
- Heat the mixture to 150 F (65 C) in the microwave. To do this microwave it for about 15 seconds at a time, mix, and check the temperature with the meat thermometer, until it reaches the desired temperature. Don't leave the meat thermomer in the dish when it is in the microwave!! (It might be possible to use higher temperatures for greater extraction, but this is what I used. You don't want the oil so hot that it chemically alters the kavalactones, which is possible because oil can get a lot hotter than water. Probably the absolute maximum temperature would be less than the boiling point of water.)
- Set the dish aside for 45 minutes or so to allow it to cool to about 80 F (27 C). You want the oil to be closer to room temperature, but still liquid.
- Strain the mixture through the strainer into the Tupperware container. Squeeze as much of the oil out as you can. Mail the oily makas remaining in the strainer to @shakas. Wash the strainer with soap to remove oily residue.
- Seal the container with the extract and refrigerate until it solidifies.
I'll post some pictures in a minute.
I just tried about a quarter teaspoon of it, and it has a very mild kava taste, and slight numbing feeling. Effects are overpowered by the real kava I am drinking so I don't know if that tiny amount actually had any effect. I tend to not be very sensitive to extract anyway..
