I bought some Feuilles de Brick for these light little tarts. The pastry has origins in Tunisia, but is popular in France, and it is light as air - lighter than filo pastry and more crunchy. The kids love how the pastry crackles when you eat it. I served these directly from the tart moulds. It was easy, and there's really no need to remove them from the moulds.
Feuilles de brick can be found in some speciality shops or online. You could use puff pastry or filo pastry for a twist on this recipe.
