To dehydrate marshmallows, place the contents of a bag of mini-marshmallows in a dehydrator, and let them sit for 8 hours. Let the marshmallows cool before using them.
- Get the marshmallows
Get a standard-size bag of mini-marshmallows. Large marshmallows can be used, but they take a full day to dehydrate.
- Put the marshmallows in the dehydrator
Spread the marshmallows across the trays of the dehydrator. Make sure that no marshmallows are stacked on top of each other.
- Dehydrate the marshmallows
Plug the dehydrator in, and set the temperature to 160 degrees Fahrenheit. Check the marshmallows after four hours to see if they are ready. It should take close to eight hours, but dehydrators vary. Store the marshmallows in a jar with a tight lid, and store them in the pantry.
