Place your hand blender and utensils in boiling water to disinfect it.
Soften the tallow over hot water or in oven at 50C, but DO NOT COMPLETELY MELT.
Add the jojoba and olive oil to the softened tallow. Mix with the hand blender until just smooth. Do not overmix, as I have found that mixing too long gives the cream a very fine texture, but it does not want to absorb into the skin as well.
Add the essential oils to the mixture and gently mix it together with a knife or spoon.
Put the tallow cream in a glass jar(s) and store in the refrigerator until needed. I would suggest keeping the big batch in the refrigerator and keeping only a small jar in your bathroom. Then re-fill as needed.
This batch makes about 300ml tallow cream.
If you have oily or break-out prone skin, replace the olive oil with 25ml organic jojoba oil.
