I do a water bath with a few rinses to make the carbon taste go away and mix it with coconut oil or butter in a crock pot set on warm for 8 to 10 hours, mixing occasionally. Really just eyeball it with the oil level until it’s like a millimeter higher than the AVB in the crock pot. At the end, we strain it thru a cheese cloth.
A lot of people do a sealed jar inside a crock pot or a boiling pot of water, but that sketches me out… The simple crock pot method works great and makes potent oil.
