A tart should be unmolded while it is hot so that the pastry dries as it cools. A tart pan with a removable bottom makes unmolding possible. Because of the false bottom, it is important to lift and move the tart pan by holding the outer rim only.
The procedure shown here may seem difficult, and many people prefer not to try it. However, if you choose not to do it, the tart will have a soggy bottom. It may take you two or three tarts to master the technique, but the results are well worth it. Once the tart has cooled, it can slide easily from its rack to a flat tart plate or platter for presentation and serving.
