This tropical cocktail is like a mini vacation in a glass-bright, fruity, and just the right amount of sweet. The Island Affair blends rum, pineapple, and coconut with a citrusy twist, making it perfect for warm evenings or whenever you want to channel beachside vibes. I’ve made this drink countless times, and it’s always a hit at gatherings. Here’s how to make it, plus a few ways to make it your own.

Island Affair
What You’ll Need
Prep time: 5 minutes
Servings: 1 cocktail
Glass: Highball or hurricane glass
Ingredients
– 2 oz (60 ml) light or gold rum
– 4 oz (120 ml) pineapple juice
– 1 oz (30 ml) coconut cream
– 0.5 oz (15 ml) orange liqueur (like triple sec or Cointreau)
– 1 oz (30 ml) fresh lime juice (about 1 lime)
– A splash of grenadine (about 1/4 tsp)
– Ice (enough to fill your shaker and glass)
– Optional garnish: pineapple wedge, cherry, or mini cocktail umbrella
Method
- Fill a cocktail shaker halfway with ice.
- Pour in the rum, pineapple juice, coconut cream, orange liqueur, and fresh lime juice.
- Shake well-about 15 seconds-until the outside of the shaker feels frosty.
- Fill your glass with fresh ice and strain the mixture into it.
- Slowly pour a splash of grenadine into the glass. It’ll sink and create a lovely sunset effect.
- Garnish with a pineapple wedge or cherry, and pop in a fun straw or umbrella if you like.
Tips & Tricks
– Use fresh lime juice-it makes a big difference in the flavor.
– If your coconut cream is too thick, stir or shake the can before using, or warm it slightly to loosen it up.
– To get that layered “sunset” look, pour the grenadine slowly along the inside edge of the glass.
– Chill your glass ahead of time for an extra refreshing sip.
Make-Ahead & Storage
– You can mix everything (except grenadine and ice) up to 1 day ahead. Store it covered in the fridge.
– When ready to serve, give it a good shake or stir, pour over ice, and finish with the grenadine and garnish.
– Leftover mix (without ice) keeps in the fridge for about 24 hours.
Ingredient Swaps
– No coconut cream? Try coconut milk for a lighter version, or even a splash of coconut water.
– Out of orange liqueur? Use a bit of orange juice or skip it entirely-it’ll still taste great.
– Want it less sweet? Cut back on the pineapple juice or skip the grenadine.
Flavor Variations
Spicy Island Affair
– Add a thin slice of jalapeño to the shaker. Muddle it slightly before adding the rest of the ingredients for a spicy kick.
Berry Island Affair
– Muddle a handful of fresh berries (strawberries, raspberries, or blueberries) with the lime juice before shaking.
Herbal Island Affair
– Add a sprig of fresh mint or basil to the shaker. Gently bruise it first to release the flavor.
Non-Alcoholic Island Affair (Mocktail)
– Skip the rum and orange liqueur.
– Add an extra ounce of pineapple juice and a splash of coconut water for balance.
Serving Suggestions
This cocktail pairs beautifully with:
Tropical Salads
– Think mango, papaya, or pineapple tossed with lime and greens. The drink’s sweetness balances the fruit’s acidity.
Grilled Seafood
– Shrimp skewers, grilled mahi-mahi, or even fish tacos go perfectly with the citrusy notes of the cocktail.
Spicy Appetizers
– Buffalo wings or jalapeño poppers? Yes, please. The Island Affair cools the heat and complements the spice.
Helpful Hints
– Don’t overdo the grenadine. A little goes a long way-it’s there more for color than flavor.
– Shake it well. You want everything creamy and well mixed. It should look smooth and slightly frothy when poured.
– Ice matters. Use fresh, clean-tasting ice. Old or freezer-burned ice can make your drink taste off.
Common Questions
Can I use bottled lime juice?
You can, but fresh really makes the drink pop. If you do use bottled, go for one without added sugars or preservatives.
What if I don’t have a cocktail shaker?
Use a mason jar with a tight lid or even stir everything together in a glass. You can also blend it for a frozen version.
Can I make it in a big batch?
Absolutely! Just multiply the ingredients by the number of servings and mix in a large pitcher or punch bowl. Add ice and grenadine just before serving.
What’s the best rum to use?
A light rum works best for a clean tropical flavor, but you can experiment with spiced or coconut rums for more depth.
How do I make it look like a pro made it?
Use a chilled glass, add that grenadine slowly, and don’t skip the garnish. A fresh fruit wedge or sprig of mint goes a long way.
Final Thoughts
The Island Affair has been my go-to cocktail for summer nights-easy to make, stunning to look at, and always a crowd-pleaser. Whether you’re sipping it solo or serving it up at a party, this drink brings a little taste of the tropics wherever you are. Try a twist, pair it with your favorite dish, or just enjoy it ice-cold on the porch. Cheers!
