Start with fresh, ripe pineapple and mango. Cut them into small chunks to make blending easier. Place the pieces into a blender and blend until smooth. If you like a bit of texture, you can leave it slightly chunky instead of making a fine puree.
Taste the fruit puree before adding anything else. If it feels slightly tangy, add honey or agave syrup. Blend again for just a few seconds until the sweetness mixes evenly. Adjust the quantity depending on how sweet your fruits are.
Wash the fresh mint leaves thoroughly and pat them dry. Place the leaves in a large pitcher or mixing bowl. Use a muddler or the back of a spoon to gently press them. This step releases the oils that give mojitos their signature fresh aroma.
Squeeze the juice of one lime directly over the muddled mint. Fresh lime juice adds zest and brightens the flavor of the mocktail. Avoid bottled lime juice, as it lacks the same freshness and tang.
Now, pour the pineapple-mango puree into the mint and lime mixture. Stir gently to combine all the flavors. Take a small taste to check balance—add more honey if needed before moving forward.
Slowly pour chilled sparkling water or club soda into the mixture. Stir gently to keep the fizz intact while evenly blending the flavors. This step makes the drink bubbly and refreshing.
Fill your serving glasses halfway with ice cubes. Pour the tropical mojito mixture into each glass, leaving some room for garnish. Stir lightly before serving to keep it well mixed.
Finish off with garnishes like lime slices, pineapple wedges, or a sprig of fresh mint. Serve immediately while the drink is chilled and fizzy. This mocktail is best enjoyed fresh, especially on hot days.
