With a potato peeler, peel the skin off of the limes and place in a clear glass bowl.
With a pairing knife, cut the ginger into quarters (lengthwise). For the vanilla beans, slice down the center to open up. Do not remove vanilla beans inside.
Add Everclear® to lime peels, vanilla beans, and ginger. Allow the mixture to steep for 2 hours, and then remove the ginger.
Add in simple syrup and stir gently until well mixed.
Allow mixture to steep for 2 more hours before using in your favorite cocktail! You will keep the lime skins and vanilla beans in your liqueur.
