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.

Etymology

Origin of marshmallow

First recorded in 1905–10; see origin at marsh mallow

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.
