The shelf life of meringue depends on various factors, such as the storage conditions, the type of meringue, and how it's packaged. Generally, fresh meringue can last for up to 2 days when stored in an airtight container at room temperature. If you want to keep it for a longer period, you can store it in the fridge or freezer.
When stored in the fridge, meringue can last for up to 5 days, but it's essential to keep it away from strong-smelling foods, as it can absorb odors easily. You can also freeze meringue for up to 3 months, but make sure to wrap it tightly in plastic wrap or aluminum foil to prevent freezer burn. Just thaw it at room temperature or in the fridge when you're ready to use it.
