Oil infusions are created by steeping herbs in oil—hot or cold—and straining for later use. Any vegetable oil will work for these infusions, however olive, almond, canola, and sesame oil work best. Herbal oil infusions can be used in cold-processed soaps, as well as for culinary uses, added to cosmetics, or as massage oil. Hot oil infusions are very versatile, making them a popular way to use herbs. Experiment with your herbs to find out what you like best!
1 C dried herbs
2 C oil
A large glass bowl
Pot holders, for safety
A pot for simmering water
NOTE: It is important that you use dried herbs for this; fresh herbs contain water, which could cause the oil to spoil and go rancid.
Over a pot of simmering water, place the bowl, and in the bowl, put the herbs and oil. Heat the mixture slowly for about three hours, over low heat—make sure the water in the pot does not evaporate completely. Next, strain the oil, let it cool, and transfer the infusion into dark glass bottles that can be sealed with a cap. Store the infusions in a dark, cool place.
