All Macarons from France are known to be quite fragile, so keeping them stored in the refrigerator will help you preserve them. Follow the steps below to store your Macarons and be able to enjoy them whenever you wish with your loved ones.
In order to retain the taste, it is advisable you eat up your Macarons within three days after purchase. Though some people say they can be easily stored for as long as 5 days. Macarons are known for their high sensitivity to air moisture. So storing them longer than 3 days will require an air-tight container placed at the lower compartment of your refrigerator. They can last for as long as 7 days without getting spoilt when stored well. But before you serve them, make sure you remove them 30 minutes before mealtime.
