Make the glaze. Add the pomegranate seeds to a blender and and blend until it looks like juice, about 10 seconds. Strain, and then pour the juice into a small saucepan and add the sugar to it. (You should have about ½ cup of the juice after straining.) Place the pan over high heat and bring to a boil. Immediately turn the heat to low and simmer until it thickens to a syrup consistency, and is reduced by about half.
Prepare the Dragon Fruit. Cut the tops off the dragon fruits (see above images). Use an ice cream scoop to scoop out as many scoops as possible from each one. Treat the tops as the lids to a pint-sized container of ice cream.
Assemble. When you serve the dragon fruit scoops, drizzle the desired amount of pomegranate syrup over it, and add about ½ teaspoon of finger lime “caviar” to each one.
Notes
If you can't get your hand on finger limes, a little fresh lime juice is great, too.
