What happens to marshmallows when you leave them in your pantry?

So you opened your marshmallows bag, grabbed what you wanted, and then put a twist tie on the bag and set the bag on your pantry shelf. The day comes when you need marshmallows again, and you pull out the bag only to find you have a gooey mess. The marshmallows left in the bag have stuck together.

What are marshmallows made of?

Marshmallows are made from a mixture of sugar (or corn syrup), gelatin, and water. The ingredients are whipped together into a spongy texture. Put simply; marshmallows are sugar and water wrapped around bubbles.

Why is moisture bad for marshmallows?

Air pockets help marshmallows keep their shape, so just a bit of moisture pumped into those air pockets makes them collapse. This is the reason why when you open your marshmallows bag, moisture from the air slips into the bag and then into the marshmallows, filling up the air pockets, ultimately dissolving and stick to one another.

How long do marshmallows last?

If unopened, marshmallows can last a long period of time, approximately 6 or 8 months. However, once you open that bag, your marshmallow shelf life can only be from 2 to 4 months when stored properly.
