Made this both per the recipe and as an equal parts drink. For me, adding an ounce of lemon juice and lime juice really balanced out the other sweet components. In fact, that oz of lime juice gives the drink a much welcomed faint bitterness.
Thinking of scaling this up for a party and including some ginger ale for zing - so I can serve one rum punch and one non alcoholic. Any suggestions for getting the perfect flavour balance?
