Make ahead: You can prep the frangipane and dough and store it covered in the fridge up to one day ahead of time. You can also prepare the tart up to 3 days ahead, wrap it well with plastic wrap, and refrigerate. Then when you are ready to serve it, take it out of the refrigerator, dust it with powdered sugar, and serve. It takes amazing served cold. (You can leave it at room temperature as well, but it will only last about 1 day.)
