1. In an 8- to 10-inch frying pan over medium-high heat, stir coconut until lightly browned, 1 to 2 minutes; pour into a small bowl. Cover and let stand at room temperature up to 2 hours.
2. In another bowl, combine whipping cream, coconut milk, and powdered sugar. Beat with a mixer on high speed until coconut cream holds soft mounds. Cover and chill up to 2 hours. Whip to blend before using.
3. Remove pan rims from crusts, and set each crust on a dessert plate. Fill crusts equally with lime curd. Top each tart with equal portions of coconut cream and sprinkle with coconut.
