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).
These Jell-O recipes, from colorful molded desserts to fruity salads, prove gelatin desserts never go out of style.
