Fresh kunafa with cream needs to be stored in the refrigerator. Since the filling is made with whipped cream and thick cream, it is perishable and should not be left sitting a room temperature for long. It will keep for up to 3 days if stored in an airtight container. If you are making your dessert ahead of time, we recommend storing the shredded pastry nests and filling separately to protect the crispness of the former. The nests may also be stored in the fridge. After they have cooled, wrap them in cling film or aluminium foil. Store them for 1-2 days.
