As early as15th 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 pig 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 the19th century, Jerry crossed the Atlantic and entered the American upper class. The demand for jelly has suddenly increased, and the market needs a simpler and more efficient method 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, grinding a large amount of dry gelatin into powder with a machine, and adding water when using it.
However, Cooper only wants to develop his industrial rubber, and he doesn't care about industrial rubber powder.
Later, Pearl and his wife Mei, who sold cough syrup in Leroy, New York, found that the demand for cough syrup was getting less and less, and they were going to "March" into the catering industry.
So, they spent some money to buy the patent of Cooper industrial rubber powder and began to make various attempts.
They added all kinds of sugar water to gelatin and tried it with people around them. Unexpectedly, it was really recognized by many people.
So they gave this food a name, and Jell-O-o was born.
