Line an oven tray with baking paper. Draw a 20cm circle on the paper.
In a small cup or bowl, combine the sugar, cornflour and cream of tartar. In a large glass or metal bowl, whip the egg whites with salt, vanilla and vinegar until soft peaks form. Gradually sprinkle in the sugar mixture and continue to whip until stiff and shiny. Mound the mixture into the traced circle on the baking tray. Flatten the top and smooth the sides using a spatula.
Place in the oven and immediately reduce the heat to 150 degrees C. Bake for 1 to 1 1/2 hours, until a pale golden colour. Turn the oven off and leave the door slightly ajar with the pavlova inside until completely cooled.
Just before serving time, invert the cooled pavlova onto a serving plate, and top with slices of banana. Cover banana with caramel sauce. Top that with whipped cream and sprinkle with grated chocolate.
You can make a simple caramel sauce by boiling a tin of condensed milk for approximately two hours. Open when cool.
just a friendly comment- after drawing a circle on the baking paper , always turn over and spread the mixture on the under side- thus avoiding the risk of food coming into contact with the "lead" from pencil or whatever other impliment is used.
I haven't yet made this pavlova but intend doing so and it does sound delicious - 19 Apr 2009
