Storage & ReheatingWill keep in the fridge for up to 3 days in an airtight container. The meringue is made from raw egg whites and stays essentially raw even after torching (which only browns the surface) — use pasteurized egg whites if possible, and take extra care if serving to pregnant, elderly, very young, or immunocompromised guests. Not recommended for freezing, as the ganache and meringue textures won't hold up once thawed.
