01 - Blend the diced mango, lemon juice, and honey in a blender or food processor until completely smooth and no lumps remain.
02 - Transfer the mango purée to a small saucepan and simmer over medium heat for 5-7 minutes, stirring occasionally, until slightly thickened. Remove from heat and let cool completely to room temperature.
03 - Place the finely chopped white chocolate in a heatproof mixing bowl. In a separate small saucepan, bring the heavy cream to a gentle simmer just until bubbles form around the edges—do not let it come to a full boil.
04 - Pour the hot cream over the chopped white chocolate. Let stand undisturbed for 1 minute, then whisk steadily until the chocolate is completely melted and the mixture is silky smooth.
05 - Add the softened butter and cooled mango purée to the chocolate ganache. Stir gently but thoroughly until fully combined, glossy, and uniform in color.
06 - Cover the bowl with plastic wrap and refrigerate for at least 1 hour. The mixture should be firm enough to hold its shape when scooped but still pliable.
07 - Using a teaspoon or small melon baller, scoop portions of the chilled ganache. Roll quickly between lightly dusted palms to form smooth balls. If the mixture sticks, lightly coat hands with powdered sugar.
08 - Arrange the shaped truffles on a parchment-lined baking sheet. Freeze for 15-20 minutes until firm to the touch, which will make coating much easier.
09 - Dip each chilled truffle into the melted white chocolate using a fork or dipping tool. Allow excess chocolate to drip off, then return to the parchment-lined tray.
10 - Immediately sprinkle the wet coating with finely chopped dried mango, coconut flakes, or pistachios while the chocolate is still tacky to ensure proper adhesion.
11 - Let the coated truffles set at room temperature for about 30 minutes, or refrigerate for 10-15 minutes if you need them to firm up faster. Store chilled until ready to serve.
