Forget the stale orange and vodka mix. This '60s cocktail recipe is a medley of lip-smacking rum, sweet passion fruit juice, tangy ruby red grapefruit, and of course, freshly squeezed orange juice. Be warned, just like a beach getaway, after one sip, you might never want to go back to the usual.
Place 1 layer of ice in a highball glass. Add pieces of pineapple and orange. Top with another layer of ice and additional layer of pineapple and orange slices. Add liquids in order given, saving grenadine as float. Garnish top with fruit slices.
