Marshmellow on a stick

A marshmallow is a fun little item that does nothing to my now knowing. The caption to the mallow is "Roast it over a campfire". It is made by buying a marshmallow from the merchant. Then you get some wood. Then use crafting to make a marshmallow on a stick.

By holding the Marshmellow on a stick over a campfire for long enough you can actually get a Roasted marshmellow which will give you the minor stat improvement buff same as the meal.
