If you have visited French pâtisseries in Paris, you know that one of the confections that always looks so beautiful are the tarts. Making one as pretty and delicious as they are in France is easier than you might imagine and each step can be done ahead of time. This tart is inspired by one of my favourite pâtisseries in Paris, Gérard Mulot in the 7th arrondissement. The pastry is similar to a rich shortbread crust and there's just a hint of mint and lemon in the custard. It is glazed with chocolate, which stops the custard from running and making the tart soggy. You can glaze it up to an hour before serving but don't refrigerate it afterward or the glaze may run.
