MANGO TART WITH COCONUT CRUST

Steps:

• Toast coconut for crust:
• Preheat oven to 350°F.
• Spread coconut in an even layer in a pie plate and toast in middle of oven, stirring occasionally, until golden, 10 to 12 minutes. (Leave oven on for baking crust.) Cool coconut to room temperature, about 10 minutes.
• Make crust:
• Pulse together flour, coconut, butter, confectioners sugar, and salt in a food processor until dough just begins to form a ball. Press dough onto bottom and up side of tart pan with floured fingers, then freeze until firm, about 10 minutes. Bake in pan on a baking sheet in middle of oven until golden, about 25 minutes, then cool completely in pan on a rack.
• Prepare filling while crust bakes:
• Purée chopped mango (2 1/2 cups) with sugar, lime juice, and a pinch of salt in a food processor until smooth, about 1 minute. Sprinkle gelatin over 1/4 cup purée in a heatproof bowl and let stand to soften 1 minute. Set bowl over a saucepan of simmering water and stir until gelatin is dissolved. Remove bowl from heat and stir in remaining purée.
• Beat cream in a large bowl with an electric mixer until it just holds stiff peaks, then fold in purée. Set bowl with filling in a larger bowl of ice and cold water and chill, stirring occasionally, until thickened, 1 to 1 1/2 hours.
• Assemble tart:
• Remove side of tart pan and spoon filling into crust, smoothing top. Chill, loosely covered, until filling is set, at least 8 hours. Before serving, let stand at room temperature at least 15 minutes but no longer than 30, then scatter diced mango over top of tart, leaving a 2-inch border around edge.
