Macadamia oil is one of the finest oils for both culinary and cosmetic use. While commercial cold-pressing requires specialised equipment, you can extract small amounts at home.
What You Need
- 2 cups raw, shelled macadamia nuts
- A high-powered blender or food processor
- A fine mesh strainer or cheesecloth
- A clean glass jar for storage
- Optional: a manual oil press
Blender Method
- Warm the nuts: Spread macadamias on a tray and warm gently in the oven at 50°C for 15 minutes. This softens the oils without cooking the nuts.
- Blend: Process the warm nuts in a high-powered blender for 10–15 minutes, scraping down regularly. The nuts will progress from crumbly to a thick paste, then eventually release their oil as a runny butter.
- Separate: Pour the mixture through a fine cheesecloth, squeezing firmly to extract the oil. You can also let it sit in a jar overnight; the oil will separate and rise to the top.
- Store: Decant the clear oil into a dark glass bottle. Store in a cool, dark place for up to 3 months.
Manual Press Method
If you have a manual oil press (available online for home use), you can feed raw macadamias directly through the press. This produces a cleaner, more refined oil. Expect roughly 70-80ml of oil per cup of nuts.
Uses for Your Homemade Oil
- Cooking: High smoke point, ideal for frying and roasting
- Skincare: Apply directly as a moisturiser or mix into creams
- Hair care: Use as a pre-wash treatment or styling serum
- Massage: Excellent carrier oil with natural absorption
The leftover pulp makes an excellent exfoliant for body scrubs or can be added to baking recipes.
