Should You Refrigerate Marshmallow Fluff After Opening?
Whether or not you refrigerate marshmallow fluff after opening is going to come down to personal preference, and context.
Marshmallow fluff does not necessarily require refrigeration after opening – it is entirely safe to leave and store at room temperature, but there are some benefits which we will now explore below.
Why You May Want To Refrigerate Fluff After Opening?
Refrigerating marshmallow fluff after opening can help preserve its shelf life for longer and keep it fresher. Plus, it’s always nice to have a chilled, creamy treat on hand when the craving strikes.
Preserve Flavor
Refrigerating marshmallow fluff after opening can help preserve its flavor.
When stored at room temperature, marshmallow fluff will start to detoeriate, more quickly – especially the warmer the environment it is kept in.
By keeping it in the fridge, you can help maintain its yummy taste and creamy consistency.
Extended Shelf Life
Additionally, refrigeration can help extend the shelf life of your marshmallow fluff.
This is particularly helpful if you don’t plan on using it all at once or if you like to stock up on your favorite treats.
Why You May Not Want To Refrigerate Marshmallow Fluff After Opening?
While refrigerating marshmallow fluff can have its benefits, there are also some reasons why you may not want to do so.
Tougher Consistency
For one, refrigeration can alter the consistency of your marshmallow fluff, making it harder to spread.
If you prefer your fluff creme to be soft and gooey, you may not enjoy it as much when it’s cold.
Your Taste Preferences
Another reason you may not want to refrigerate marshmallow fluff after opening is that it’s just a matter of personal preference.
Some people prefer their fluff creme at room temperature, and that’s totally okay!
If you find that you don’t like the taste or texture of refrigerated marshmallow fluff, you can always store it at room temperature instead.
How Long Will Marshmallow Fluff Last In The Fridge?
Refrigerated marshmallow fluff can last for several weeks to several months, depending on the brand, where you place it in the fridge, how often it is opened and how well it is kept sealed.
As a general rule of thumb, you should always check the expiration date on the packaging and follow any storage instructions provided.
If your marshmallow fluff starts to look or smell off, it’s best to err on the side of caution and throw it out.
Lastly
So there you have it, fellow marshmallow lovers – everything you need to know about refrigerating marshmallow fluff after opening.
Whether you prefer your fluff creme chilled or at room temperature, the most important thing is to enjoy it to the fullest!
What that looks like for you, of course, will depend!
