National Rocky Road Day is observed on June 02, 2018. It's a day to eat Rocky Road ice cream or dessert, which is made of chocolate, nuts, and marshmallows. The original Rocky Road ice cream used chocolate ice cream with no chocolate chip pieces. Today, Rocky Road can be obtained based on vanilla ice cream with chocolate chips, marshmallows and almonds.
Rocky Road dessert was invented in Australia in 1853 as a way of on-selling confectionery spoiled by the long journey from Europe. Gold miners in towns outside of Melbourne, such as Ballarat, were wealthy but uncultured. Unscrupulous businessmen took advantage of these men, mixing the spoiled confectionery with low quality chocolate and other 'filler' ingredients, such as locally foraged nuts. The name Rocky Road is derived from the 'Rocky Road' travelers had to take to get to the gold fields.
The most popular version of Rocky Road in the U.S. is in ice cream form, which consists of chocolate ice cream, marshmallows (or sometimes a "marshmallow swirl"), and nuts. Although not as popular, slabs of Rocky Road can also be found at confectioner's shops. The Annabelle Candy Company manufactures a candy bar called Rocky Road that has marshmallow, a thin covering of chocolate, and cashews. (With material from: Wikipedia)
