In a medium bowl, stir to combine water and gelatin. Set aside for 5 minutes.
Meanwhile, blend mango in a food processor or blender until smooth. This should yield about 1 cup of puree.
In a small pot over low heat, stir to combine ½ cup mango puree, honey, lemon juice, and salt. Bring to a simmer. Reserve remaining ½ cup mango puree.
Add gelatin mixture to pot and stir until dissolved. Remove from heat.
Divide mango-gelatin mixture evenly between two bowls. Set one bowl aside.
To remaining bowl, stir in reserved ½ cup mango puree.
Transfer the mixture with the extra 1/2 cup mango puree to a piping bag or squeeze bottle. Set aside.
To make your own mango-shaped molds, spread cornstarch evenly into a 9x13-inch rimmed baking sheet or dish.
To make the mold, glue a large dried lima bean to a cake pop stick or wooden skewer.
Once the bean is set, press into the cornstarch to create 45 mango-shaped wells.
Use your piping bag or squeeze bottle to fill each well with mango mixture.
Freeze for 15 minutes or until gummies are firm.
Line a small baking sheet with parchment paper.
Transfer mango gummies to a medium bowl and rinse with cold water to remove excess cornstarch. Drain and transfer to a parchment-lined baking sheet.
Warm the remaining bowl of mango-gelatin mixture in the microwave or over a double boiler if needed, just until smooth. Do not let the mixture exceed 200 F.
Dip gummies one by one into mango mixture. Transfer each gummy back to the parchment-lined baking sheet as you go.
Refrigerate for at least 2 hours or overnight.
"Peel" and enjoy your gummies. Remember: the peel is edible, too!
