Tarts are more than just pies without tops. They can have a variety of doughs, fillings, and flavors. Common tart doughs include pate brisee (similar to pie dough), short doughs, pasta frolla, brioche, and puff pastry. Tarts are assembled either by placing a pre-made filling into an unbaked shell or by combining the filling with the shell before baking. Proper techniques for rolling out dough and blind baking shells are described. Finally, the document discusses popular tart fillings and flavors that can be combined.
