01 - Blend the diced mango, lemon juice, and honey in a blender or food processor until completely smooth and no chunks 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 chopped white chocolate in a heatproof bowl. In a separate saucepan, bring the heavy cream to a gentle simmer—do not let it boil. Pour the hot cream over the chocolate and let stand for 1 minute.
04 - Stir the cream and chocolate mixture with a heatproof spatula until smooth and glossy. Add the softened butter and cooled mango purée, stirring until fully incorporated and the ganache is uniform in color.
05 - Cover the bowl with plastic wrap and refrigerate for at least 1 hour, or until the mixture is firm enough to hold its shape when scooped.
06 - Using a teaspoon or melon baller, scoop portions of the chilled ganache and roll them into smooth balls between your palms. If the mixture sticks to your hands, lightly dust them with powdered sugar.
07 - Arrange the shaped truffles on a parchment-lined baking sheet. Freeze for 15-20 minutes until firm and cold to the touch, which makes coating easier.
08 - Dip each chilled truffle into the melted white chocolate, using a fork to lift and let excess chocolate drip off. Return to the parchment-lined tray.
09 - While the chocolate coating is still wet and tacky, sprinkle with finely chopped dried mango, desiccated coconut, or chopped pistachios as desired.
10 - Allow the coated truffles to set at room temperature for about 30 minutes, or refrigerate for faster setting. Store refrigerated until ready to serve.
