Happy National Ice Cream Sandwich Day! While most of us relate to the original rectangle of vanilla ice cream sandwiched between two soft chocolate cake pieces, other around the world do not. In Australia, the most popular sandwiches are called “Giant Sandwiches," while "Maxibons" are half-dipped in chocolate. The most exotic ice cream sandwiches might be found in Singapore. Here, red bean, yam, and honeydew are all popular flavors.
