Combine: Place the mango chunks, lime juice, and maple syrup into a high-speed blender or food processor.
Blend: Add about half of the water and blend on high until the mixture is perfectly smooth. If the blender is struggling, add the remaining water one tablespoon at a time. The mixture should be thick but pourable.
Adjust: Taste the mixture. If it needs more brightness, add a little more lime. If it’s not sweet enough, add another splash of maple syrup.
Fill: Pour the purée into your ice pop molds, leaving about a half-inch of space at the top to allow for expansion.
Set: Place the lid on the molds and insert the wooden sticks.
Freeze: Place the molds in the freezer for at least 6 hours, or ideally overnight.
Serve: To remove, run the molds under warm water for 10–15 seconds until the popsicles loosen. Gently pull the sticks and serve immediately.
