Pictured here is the Pavlova, a meringue-based dessert that is named after the legendary Russian ballerina Anna Pavlova. With a crisp crust and soft, light inside, it is usually topped with fruit and whipped cream. This dessert is believed to have been created in honour of her after her tours to these countries in the 1920s. However, the nationality of its creator has been a source of argument between the two nations for many years. What two countries, with a sporting rivalry too, are we referring to here?
