Ingredients:

  • 3/4 pint (0.75 pint) Carrier Oil of your choice, see written
  • 1 oz (1 oz) Rosemary dry or fresh

Instructions:

  • Pour your oil into your sauce pan or crock-pot (slow cooker).
    3/4 pint Carrier Oil
    Carrier oil is poured into a saucepan
  • Then, add your rosemary to the oil. The rosemary must be completely covered with oil, and be at least an inch or two above the rosemary. 
    1 oz Rosemary
    Rosemary sprigs are added to the pan
  • Place on a low heat at around 140f ( 60c) as we do not want to be frying the rosemary just extracting its goodness. If you are using your stove or hotpot like I am, this should take between 1 to 2 hours, a crock pot will take longer than possibly around 2 to 5 hours. Do not cover or apply the lid as this will produce condensation, allowing water to enter the oil.
    The pan is placed onto the heat
  • Once the oil has taken on the scent of the rosemary. Turn off the heat and allow the oil to cool.
    The pan is removed from the heat
  • Once the oil has cooled, it will need to be strained using cheesecloth or a fine strainer. If your rosemary herb is still attached to the stem, like ours, it is easily removed with kitchen tongs. Otherwise, you may need to squeeze it through the cheesecloth or strainer several times to fully remove the rosemary.
    The rosemary oil is seperated from the spent rosemary sprigs
  • Transfer into a sterile container and store in a cool dark place.
