Yum and I have been celebrating summer by making our delicious variations of ice cream sandwiches, but today, August 2, is National Ice Cream Sandwich Day! It is believed that the ice cream sandwich was invented in the Lower East Side of New York City in 1900. According to an article in the Washington Post, the ice cream sandwich man, whose street cart was "elaborately decorated with signs in Hebrew characters," made sandwiches quickly with a tin mold. His little stand was so popular, he had no time to make change and insisted on getting the exact price of the sandwiches. The original cost was 1 cent and the cookie was a tiny slab of water wafer. After this, ice cream sandwiches became more mainstream and in 1926 the first patent was given to an ice cream sandwich making machine. So go out and celebrate!
