Crush a clean, dry avocado pit with a mallet, then strain oil out of the pit pieces. Clarify the oil and remove any contaminants on top. Heat the oil to 250 degrees Fahrenheit to kill bacteria and remove water.
- Prepare the pit
Slice the avocado in half lengthwise to expose and remove the pit. Wash the pit completely so no remnants from the avocado remain. Set the pit out to dry. If possible, place the pit under a light to speed up drying time. It can take up to a few days for the pit to be entirely dried.
- Extract the oil
Place the dried pit into a plastic bag. Use a mallet to strike the pit and crush it into pieces, pouring any resulting oil into a jar. Pour the crushed pit pieces into a mesh strainer or cheesecloth placed on top of the jar and push or squeeze the oil through.
- Clarify the oil
Let the oil sit for one or two days so any contaminants can float to the top. Use a spoon to remove the contaminants. To kill bacteria and remove excess water, you will need to heat the oil to 250 degrees Fahrenheit before using.
