🍦 Ice Cream Day – A Chilling History of the World’s Favorite Treat

1. Ancient Persia's Snowy Delicacy

As early as 400 BCE, people in ancient Persia collected snow and preserved it to create a refreshing dessert. They would mix it with rosewater and vermicelli (a kind of noodle), topping it with fruits and spices.

Some legends also claim that Julius Caesar and Alexander the Great enjoyed snow mixed with milk and honey—an early precursor to ice cream!

2. The Roman Emperor and Eternal Snow

In the Roman Empire, Emperor Nero famously sent slaves to the mountains to collect fresh snow. He mixed it with fruits, honey, and nuts, enjoying a luxurious frozen dessert centuries before refrigeration.

3. China's Creamy Innovation

The earliest use of dairy in frozen desserts may come from ancient China’s Shang dynasty, where buffalo milk was mixed with rice and snow.

Explorer Marco Polo later recorded tasting similar icy confections during his travels in Yuan Dynasty China, helping spread the idea of dairy-based ice cream to Europe.

4. The Scientific Breakthrough: Saltpeter and Ice

In the early 1500s, scientists began experimenting with saltpeter (potassium nitrate) and ice to achieve subzero temperatures.

Marcantonio Zimara discovered that mixing potassium nitrate with water absorbed heat and cooled the mixture.

Later, Bernardo Buontalenti of Florence created a device that used this principle to reach temperatures as low as -200°C, revolutionizing how ice cream was made.

5. Charles I and the Royal Cream

The first person known to enjoy a modern-style dairy ice cream may have been King Charles I of England in the 1600s.

His French chef, Gerard Tissain, is believed to have crafted a dessert using milk and cream—creating a sweet sensation that soon spread across Europe.

6. The Birth of the Word "Ice Cream"

In 1718, the phrase “Ice Cream” first appeared in the British cookbook Mrs. Mary Eales's Receipts.

By 1744, the term was officially included in the Oxford English Dictionary, and the dessert had become a staple of European dining.

🍧 [Fun Fact] How Did People Beat the Heat Before Freezers?

Before modern refrigeration, people relied on mountain snow, saltpeter, and clever insulation to keep things cool. Ice houses, snow pits, and natural caves were used to store ice throughout the summer!

May 9th may be a local holiday in Japan, but ice cream’s story is truly global—a tale of snow, science, and sweet invention.

Take a moment today to chill out, just like emperors and explorers once did! ❄️🍨
