The main ingredient is patience! Other than that you will need fifth of whiskey, a little Amaretto, some lemon peels, and Bing cherries. And mason jars!
Evenly divide the cherries between the jars and then add 1 to 2 Tbs of Cherry Juice along with a few lemon peel strips.
Fill the jars with the whiskey and close tightly. You can use whiskey, rum, brandy, or any other liquor you have laying around!
