Usage
What is the Marshmallow Test? The Marshmallow Test is a famous psychological test performed on young children in the 1960s linking delayed gratification (a treat right now … or two later?) to success later in life. A 2018 replication notably concluded, though, that socioeconomic background significantly influenced the ability of children to delay their gratification. So the test was biased.

Explanation
A marshmallow is a sweet, soft treat. Marshmallows are sometimes melted and turned into a sugary topping for ice cream or a filling for baked goods. Marshmallows are made of gelatin and sugar, with a dusty powdered sugar surface, and they squish like a sponge when you squeeze or bite down on them. Marshmallows can be toasted over a fire to turn them slightly crisp on the outside and melty within, and sandwiched between graham crackers with chocolate to make a "s'more." The original 19th century marshmallows were made from a plant called mersc-mealwe (marsh mallow plant) in Old English.
