Preheat the oven to 150oc.
You need 6-8 circles of meringue to build the tower in increasing diameter. I drew onto baking parchment 7 circles ranging from 15cm down to 4cm. Once the circles are drawn, turn the parchment paper over as otherwise the pen or pencil will transfer onto the meringue.
Place the parchment onto baking trays.
Place the egg whites into a stand mixing bowl and mix on medium until frothy. Gradually add the sugar then mix on high speed for five to six minutes until thick and glossy.
Add in the vinegar and cornflour and mix again until just combined.
The meringue should be stiff.
Place the mixture into a piping bag with a star nozzle fitted and pipe in circles on the parchment. I leave a centimetre border before the pencil line so that i can add a decorative edge. Remember that the meringue will expand as it cooks so do not draw too close together.
I like to do two layers of meringue to add height and stability.
Place into the oven then immediately turn the oven down to 120. Allow to bake for one hour then turn the oven off.
Allow to cool for two to three hours in the oven (the longer the better) then remove and allow to cool completely on the baking trays.
Whilst the meringue is baking, make the raspberry sauce by placing the raspberries and sugar into a pan on a medium heat. Crush the raspberries with a fork and allow to simmer for 5-6 minutes. Blend then pass through a sieve to remove the seeds. Set aside to cool.
Place the cream, sugar and vanila extract in a bowl and whip until you have stiff peaks. Soft peaks will not be stable enough for this so ensure it is whipped sufficiently.
Place the cream into a piping bag with a star nozzle attached.
Time to assemble. Starting with your largest circle, place it onto your serving plate and pipe with the cream.
Place strawberries and raspberries on top of the cream, drizzle with some raspberry sauce then place the next layer of meringue.
Continue to do this using the meringue in descending size order.
I like to place a wooden skewer in the centre to hold the structure in place. I then just slide each meringue onto the skewer as i build.
Ensure your fruit is in a even layer on the cream to ensure that each layer can sit flatly.
I like to top my pavlova with a Christmas star and sprinkle red sugar sprinkles to make it extra festive.
