In food processor, briefly pulse flour, almonds and sugar. Add butter and process until butter is thoroughly blended and mixture resembles fine crumbs.
Remove about one half of the mixture to a small bowl. Add coconut, and toss to combine. Set aside.
Press remaining mixture evenly into the bottom of a 9x13-inch glass baking dish.
Bake for 15-20 minutes, or until lightly golden. Remove from oven.
Evenly spread Lemon Curd over crust. Sprinkle the rest of the flour-coconut mixture over the curd.
Return to oven and continue baking for 25 minutes. Check occasionally during the last round of baking to make sure that the coconut doesn't burn.
