01 - Purée the mango, lemon juice, and honey in a blender until completely smooth.
02 - In a small saucepan over medium heat, gently simmer the mango purée for 5–7 minutes until slightly thickened. Let cool to room temperature.
03 - Place the chopped white chocolate in a heatproof bowl.
04 - In another small saucepan, bring the cream to a simmer (do not boil). Pour the hot cream over the chocolate. Let stand for 1 minute, then stir until smooth.
05 - Stir in the softened butter and cooled mango purée until well combined and glossy.
06 - Cover the bowl and refrigerate the mixture for at least 1 hour, or until firm enough to scoop.
07 - Using a teaspoon or melon baller, scoop portions of the mixture and roll into balls with your hands. If the mixture is too sticky, dust your hands with a little powdered sugar.
08 - Place truffles on a parchment-lined tray and freeze for 15–20 minutes to firm up.
09 - Dip each truffle in melted white chocolate to coat. Place back on the tray.
10 - While the coating is still wet, sprinkle with dried mango, coconut, or pistachios if desired.
11 - Allow truffles to set at room temperature or refrigerate until firm.
