For the fruits: Drain well and combine all fruits in a large bowl.
For the Pandan Jelly: Slowly sprinkle unflavored gelatin in liquid measuring cup filled with 1/2 cup water; let bloom for a minute. Zap mixture in microwave 1 minute (may need to zap more in 10 seconds intervals) to fully dissolve gelatin. In a medium mixing bowl, mix sugar and coconut juice. Stir in buco pandan extract, green food coloring and dissolved gelatin mixture, whisking well to combine. Transfer to a Pyrex square dish and refrigerate overnight until set to a firm but soft gel.
For the dressing: Whisk all ingredients in a medium mixing bowl to mix well.
Cut jelly into nice chunks and gently mix with the fruits. Pour pistachio dressing in fruits, slowly tossing well. Transfer to plastic containers and freeze away. And then "grin"! That's easy...and be ready for recipe requests at the party.
