How to Make Mint Infused Olive Oil for Soapmaking

I enjoy being able to add a little “extra” to the soaps I make.  You would think that providing the goat milk would be enough, but sometimes I am a little #EXTRA and also include garden vegetables and herb infusions to make our soap even dreamier.

Last month, Lesley from Solway Farms shared some of her excess mint with us – in trade for some soap at a later date.  The first step is to infuse some olive oil with this beautiful mint.

Dehydrating the mint

Using my brand new Hamilton Beach dehydrator,  (affiliate link) I wanted to test which would work out better:   I added some to the dehydrator tray while it was still on the stalk, and on a separate tray I picked the leaves first.

I set the controls on the dehydrator to 100° and 5 hours, and went about my day.

Later that evening, the mint was dried and ready for the next step.

(You can see I added the smaller, picked leaves to the special “herb tray” that was included with the dehydrator.)

Infusing the oil

First, I started a water bath in a large pot on the stove.  I felt I had enough mint to infuse 3 quart-size jars of olive oil, so I laid 3 jar sealing rings in the bottom of the pot.  The rings keep the jars from having direct contact with the bottom of the pot, and allows for a more even heat distribution.

I divided the mint into these 3 jars, and then filled them with Olive Oil – leaving about 1″ of headspace.  (Although these jars will not be “canned,” I wanted to be sure that the oil had plenty of room to bubble and expand during the heating process.)

I set the jars on the sealing rings, filled the pot with water, and then turned the burner to low heat.  I let the mint steep in the heated oil for about 3 hours, and then I turned off the burner, carefully added a sealing lid and ring to the top of the jars, and let them sit overnight.

The next morning, I removed the completely cooled jars, tightened the sealing rings, and set the jars in a warm corner of my soap room away from direct sunlight.

I’ve been shaking these jars a bit every day, and plan to do so for a few weeks.   Stay tuned for the next steps in the process!
