NATIONAL VANILLA MILKSHAKE DAYOn June 20th each year, National Vanilla Milkshake Day celebrates the cold beverage made with vanilla ice cream, vanilla, and milk.This frosty drink didn’t begin with those three ingredients, though. In 1885, the term “milkshake” showed up in print for the first time. The concoction of cream, eggs, and whiskey was often served with other alcoholic tonics such as lemonades and soda waters. It has a long history of how it began .Anyway if you like it ,drink and celebrate this nice one .
