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 allow to cool completely to room temperature.
03 - Place the finely chopped white chocolate in a heatproof mixing bowl and set aside.
04 - In a separate small saucepan, bring the heavy cream to a gentle simmer. Do not let it come to a full boil.
05 - Pour the hot cream over the chopped white chocolate. Let stand undisturbed for 1 minute, then stir with a heatproof spatula until the chocolate is completely melted and the mixture is smooth and glossy.
06 - Add the softened butter and cooled mango purée to the chocolate mixture. Stir gently but thoroughly until fully incorporated and the ganache is uniform in color and texture.
07 - 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.
08 - Using a teaspoon or melon baller, scoop portions of the chilled ganache. Roll each portion between your palms to form smooth balls. If the mixture sticks to your hands, lightly dust them with powdered sugar.
09 - Arrange the shaped truffles on a baking sheet lined with parchment paper. Place in the freezer for 15-20 minutes until firm and cold to the touch.
10 - Dip each chilled truffle into the melted white chocolate, using a fork to gently lift and coat completely. Allow excess chocolate to drip off, then return to the parchment-lined tray.
11 - While the chocolate coating is still wet, sprinkle with finely chopped dried mango, desiccated coconut, or chopped pistachios as desired.
12 - Allow the coated truffles to set at room temperature for 30 minutes, or refrigerate for faster setting. Once firm, they are ready to serve.
