The Dr. is in... my cocktail!
Don't throw away your flat Dr. Pepper... upcycle that soda and make a brilliant cocktail!
2 oz. of your favorite white rum
4 oz flat Dr. Pepper (flat is best because you'll get a better shake)
Muddle raspberries in a shaker, add white Rum and 4 oz flat Dr.Pepper…. add ice and shake. Fine strain into a cocktail glass and garnish with fresh raspberries.
