Categories: Kids, Vegetarian The variations on crostata are endless as the crust can be more biscuit-like such as in this recipe or cake-like. It can be thin or thick and made with ground nuts (I use hazelnuts here) or flavoured with cocoa, lemon, vanilla or spices. The filling can be any fruit jam whatsoever. The only limitation is your imagination. When I make short crust I usually make double the recipe and freeze what I don't need so that I can make a crostata with jam from the refrigerator at last minute if needed. The pastry can also be cut into shapes to make biscuits topped with the jam and sandwiched with another piece of pastry with a window cut into it.
