Hand crafting the perfect Martini has never been easier. Simply add 15 oz of Vodka or Gin, your preference; then shake twice a day for three days and strain liquid out. Add two oz. of infused spirit to shaker with ice, shake, shake it baby, and pour! You can refill infusion kit for a second infusion, just let it sit a week the second time. Tip: Snap sugar cube in half and save for second infusion.
