Sidewinder's Fang peel (orange peel shaped like a snake)
1 1/2 oz. fresh lime juice
1 1/2 oz. fresh orange juice
1 1/2 oz. passion fruit syrup
3 oz. seltzer
1 oz. blended aged rum
1 oz. black blended rum
Garnish: Mint sprig
Line a snifter with the Sidewinder's Fang peel, with one end hanging over the rim of the glass. Fill glass with cracked or cubed ice to hold the peel in place. Put the remaining ingredients in a drink mixer tin with 12 ounces of crushed ice and 4 to 6 small "agitator" cubes. Flash blend then strain into the snifter. Garnish with a mint sprig.
