Combine the full-fat coconut milk, granulated sugar, fresh lime juice, lime zest, vanilla bean paste, sea salt, and water in a large mixing bowl. Whisk everything together for a full minute—I always get impatient here, but the sugar needs those extra seconds to dissolve completely, which is why your popsicles won't develop ice crystals later.
In a separate smaller bowl, whisk together the coconut cream and agave syrup until it reaches ribbon consistency (about 2 minutes of steady whisking). This step matters because you're creating the swirls that make these beautiful tropical frozen treats so visually stunning when people pull them from the freezer.
Fold the coconut cream mixture into the base mixture using a rubber spatula in three stages—add one-third, fold gently until combined, then repeat. Never stir or mix aggressively here because you want to keep those cream streaks intact instead of blending everything into beige soup.
Divide the diced mango between eight popsicle molds, adding about 1 tablespoon to each cavity. I learned this trick from Marco's pastry chef friend: mango at the bottom creates a surprise texture pop when guests bite through, and kids go absolutely wild for it.
Pour the coconut mixture carefully over the mango, filling each mold to about 1/2 inch from the top. Leave that gap because the mixture expands slightly as it freezes, and you don't want overflow on your freezer shelf.
Insert popsicle sticks into each mold, then top each one with a small pinch of shredded coconut and a couple ginger specks. This is where I usually step back and feel like I'm creating edible art—those tiny coconut flakes catch light once frozen.
Freeze for at least 24 hours before removing from molds. I use the hot water trick: run warm (not boiling) water over the outside of each mold for 10 seconds, then gently twist the popsicles out onto parchment paper. This prevents broken sticks, which is the only real tragedy with homemade frozen treats.
