Gather your lemons, zest peeler, clean jar and lid, parchment paper and a label.
Use a zest peeler to peel the colorful skin off of the lemons, avoiding the white pith underneath.
Fill your clean jar with as many lemon peels as desired.
Add the vodka or your alcohol of choice. Add enough alcohol to submerge the lemon peels. 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 lemon extract in a cool, dark place and allow it to extract for 6-8 weeks.
Every few days, give your jar of extract a shake to help aid the extraction process.
When the extraction time is up, check you extract. If you feel like it needs to be stronger, simply give it a little more time until you're satisfied with the finished product.
If desired, transfer to smaller bottles that are convenient to use.
Keep your lemon extract stored in a cool, dark place for the best shelf life.
Enjoy!
