Jelly was invented by Peter Cooper.

As early as the 15th century in Europe, people began to eat jelly. At that time, jelly was only available in some high-end restaurants. Early jelly ingredients, mainly collagen, were obtained by boiling animal bones or boiling pig's ears and trotters.

of course, this processing method obviously takes a lot of time, usually several hours, and the labor and material costs are very high. But perhaps this is one of the reasons why it can become a high-end food.

Later, in the 19th century, jelly crossed the Atlantic Ocean and entered the upper class in the United States. The demand for jelly suddenly increased, and the market needed a simpler and more efficient way to make jelly.

As a result, people spared no effort to start inventing various jellies. Soon, a man named Peter Cooper invented an industrial gelatin powder.

his method is simple and rude, that is, a large amount of dried gelatin is ground into powder by a machine, and when it is used, just add water.

However, Cooper only wanted to develop his industrial glue, and he didn't take industrial gelatin powder to heart.

Later, Pearl Waite and his wife Mei, a couple who were selling cough syrup in Leroy, new york, found that the demand for cough syrup was getting less and less, and they were ready to "March" into the catering industry.

So, they spent some money to buy the patent of Cooper's industrial gelatin powder and began to make various attempts.

They added all kinds of sugar water to gelatin, and asked people around them to try it. Unexpectedly, it has really been recognized by many people.

so, they gave this food a name, and Jell-O-o was born.
