                Crank your oven up to 350°F and let it get hot.

                Dump the crumbs, salt, brown sugar, and toasted coconut into a big bowl. Stir 'em up so it’s all even, then pour in that melted butter. Keep mixing till it looks like wet sand.

                Press your crust into the bottom and sides of a 9-inch pan. Bake it for 10 minutes, so it just starts to turn golden. Fix any weird edges with a spoon while it’s still warm.

                Turn the oven down to 325°F. In a heat-safe bowl, whisk your mango puree, lime juice and zest, vanilla, sugar, a pinch of salt, and all those yolks till it’s totally smooth.

                Set the bowl over a pan of simmering water (double boiler style). Keep whisking for about 20 minutes. When it’s thick and coats the back of a spoon, pull it off heat and stir in all the butter, a little at a time, till it’s smooth and glossy.

                Pour that silky curd into your baked crust and smooth it out. Bake for about 15–17 minutes so it sets, but wobbles a touch in the middle.

                Put the tart on a rack to cool off, then stick it in the fridge for at least 4 hours—overnight's even better. That way, it sets up firm.

                Pile on Swiss meringue, mango slices, coconut bits, and lime wedges right before serving. Use what you like!
