A marshmallow is a sweet treat that's often toasted or roasted over a fire.
You might know marshmallows as those fluffy white things that kids love to put on top of hot chocolate or s'mores. But they're also used in baking, sometimes as a topping for desserts like rice crispy treats or cakes. If you have a recipe that calls for marshmallow cream or mini marshmallows, it's probably because the recipe wants that sweet and airy texture. You might even see them called "whipped marshmallow" if they're beaten up to be super light and fluffy.
A species of mallow, Althaea officinalis, that grows in marshy terrain.
To soften (literally or figuratively)
