Flan Parisien is a French custard tart also known as Flan pâtissier which is quite popular in France, in fact you will find them in most patisserie shops. Some are better than others but making it fresh yourself, will not compare. It’s easy to make, even the pie crust (See my recipe) however you can always buy it or use puff pastry if short on time. A great snack or dessert to enjoy with a sweet white wine such as a chilled muscat de Rivesaltes.
