Fill a rocks glass with ice to chill and set aside. Add 1 sugar cube to a mixing glass then 2 dashes of orange bitters. Muddle the sugar cube to a paste in the mixing glass. Add 3 oz. of a bottled cocktail mixture made with Rittenhouse Rye, Strega and Apostles Palo Cortado Sherry. Fill the mixing glass with ice and stir for 20 or 30 seconds to chill and dissolve as much of the sugar as possible. There will be some left over which is good. Dump the ice out of the glass that you've been chilling and strain the drink into the chilled rocks glass. Twist an orange peel over the surface drink, rub it around the rim and then discard the peel. Smile, serve.
