Tarts are an elegant subcategory of pie. The pastry, which is typically baked in a short-sided fluted pan, isn’t flaky like a pie crust; instead it’s sweet and has a closed crumb, reminiscent of shortbread. The filling for tarts is often creamy and rich and can be baked with the tart shell, like in a Lemon Tart; added after, as with a Fresh Fruit Tart; and sometimes topped with fruit, like in French Apple Tart.
