Peel and chop mangoes and pineapple into bite-sized chunks—about 2 cups total, in about 5 minutes.

In a blender, combine fruit chunks with 1 cup cold water and 1 tbsp fresh lime juice. Blend on high until smooth, about 45–60 seconds.

Taste the juice and drizzle in 1–2 tsp honey or agave syrup. Pulse briefly, then blend 10 more seconds to meld flavors evenly.

For an ultra-smooth juice, press through a fine-mesh strainer into a pitcher. Use a spoon to press pulp, catching only silky golden liquid.

Fill tall glasses with ice cubes and pour the vibrant juice over. Garnish with mint leaves or a lime wheel—serve immediately for peak refreshment.
