Three flavors of marshmallows from one base recipe: we'll make vanilla, chocolate, and raspberry marshmallows. This is a gelatin based recipe that is super fluffy, stable enough to cut into shapes if you like, and stores very well.
How to store homemade marshmallows
Homemade marshmallows last at least a few weeks when stored properly. You can use either a large airtight container or ziplock bag, like I do.
The cornstarch aids in removing the stickiness of the marshmallow by adsorbing moisture, so thoroughly coating them is key. And to ensure that they stay in the shapes you cut, it's a good idea to store them in layers.
Lay down a single layer or marshmallows, then cover them with some wax or parchment paper. Place another layer of marshmallows on top and repeat this process as necessary. I do this inside ziplock bags.
