In ancient Egypt, kitchens were an integral part of daily life. While they didn't have a built-in slushie machine, they did have access to natural resources that allowed them to create refreshing drinks. The Egyptians would use the Nile River's water to make fruit-based beverages. They would crush fruits like pomegranates, grapes, and figs, and mix them with water to create a delicious and cooling drink. These fruity concoctions provided relief from the scorching Egyptian heat.
