The dessert was especially popular in the first half of the 20th century. The original gelatin dessert began in Le Roy, New York, in 1897, when Pearle Bixby Wait trademarked the name Jell-O. He and his wife May had made the product by adding strawberry, raspberry, orange, and lemon flavoring to sugar and granulated gelatin (which had been patented in 1845). The powder is mixed with boiling water and then cooled to produce a gel.
