Gather your cinnamon sticks, clean glass jar and lid, parchment paper and a label.
To your clean jar, add your cinnamon sticks. I recommend filling the jar as full as possible for maximum flavor. You can break the sticks if you need to make them shorter to fit your jar.
Pour in your vodka or your alcohol of choice. Use enough liquid to completely cover the cinnamon sticks. Leave a bit of head space at the top of the jar.
Place a piece of parchment paper between the jar and lid to prevent possible corrosion from the alcohol touching the metal lid.
Seal the jar closed.
Label the jar with the product name, start and end date.
Place the jar of extract in a cool, dark place and allow it to extract for 6-8 weeks for the strongest cinnamon flavor.
Every few days, give your extract jar a shake to help aid the extraction process.
When the extraction time is up, check your extract. If you feel like it needs to be stronger, simply give it a little more time until you feel that it has reached the appropriate strength.
If desired, transfer your extract to smaller bottles that are convenient for use.
Store your extract in a cool, dark place away from direct sunlight.
Enjoy!
