As an Aussie, may I offer you our Pavlova and Lamingtons as possible choices to represent our fair country?
Pavlova is egg whites and sugar whipped until fluffy and baked in a slow oven. The shell is crispy like a merangue and centre is a delicious sweet mushy cloud of yum. The whole thing is topped with whipped cream and fresh fruits (usually strawberries, kiwifruit and passionfruit). It is my family's first choice of dessert for Christmas time or any special occassion.
Lamingtons are sponge cake squares dipped in warm chocolate icing and rolled in dessiccated coconut. Usually a morning or afternoon tea treat.
