Place 1 sugar cube each in the bottom of 2 old fashioned glasses. Add 2-3 dashes of cherry bitters over each sugar cube. Add 1/2 ounce tart cherry juice to each glass. Crush sugar cubes with muddler or bar spoon until completely broken. Fill each cup half way with large ice cubes. Add 1 ounce of bourbon to each glass and stir the cocktails 6-8 times. Add a bit more ice and 1 more ounce of bourbon to each glass. Stir another 6-8 times or until cocktail is chilled and sugar looks dissolved.

Garnish with orange peel and frozen tart cherries.
