In a medium bowl, combine graham cracker crumbs, kosher salt, brown sugar, and toasted coconut. Pour in the melted butter and mix until everything is evenly moistened.

Press the mixture firmly into a 9-inch tart or pie pan, covering the bottom and sides evenly. Use a flat-bottomed measuring cup or glass to help press it down firmly.

Bake the crust for 10 minutes. If the crust has slumped or changed shape, you can adjust it while it's still warm using a spoon or measuring cup.

Lower the oven temperature to 325°F (165°C).

In a heat-proof bowl, combine the mango puree, lime zest, lime juice, vanilla extract, granulated sugar, salt, egg yolks, and 4 tablespoons of butter.
07 -
Place the bowl over a pot of simmering water (double boiler method), making sure the bottom of the bowl doesn't touch the water. Stir constantly with a whisk until the mixture thickens enough to coat the back of a spoon, about 20 minutes. Then stir in the remaining 4 tablespoons of butter until smooth.

Pour the curd into the pre-baked crust, smooth the top with a spatula, and bake for 15-17 minutes until just set but still slightly jiggly in the center.
09 -
Let the tart cool completely to room temperature, then chill in the refrigerator for at least 4 hours or overnight.
