Preheat oven at 180C. You will be turning this down to 120C when the pavlova is put in to bake.
Whisk the egg whites on Low speed until soft peaks.
Switch to Medium speed and gradually whisk in the sugar.
Once all the sugar is added, switch to High speed and whisk until stiff peaks. The meringue should be shiny and glossy.
Add in the cornstarch, vinegar and vanilla extract. (Note: I like to dissolve the cornstarch with the vinegar and add in as a mixture so that there are no lumpy bits of cornstarch in the meringue.)
Transfer the meringue into a piping bag with a large piping tip. Or you can just cut off the tip of the piping bag and use it without a piping tip, that works too.
To make the Christmas wreath, using a tube pan insert as a guide, cut a hole in the baking parchment and place it over the tube pan. Pipe the meringue around the tube pan insert in circles to make a wreath.
Using a spatula or a butter knife, mould the meringue to make the outer sides higher. Gently smoothen and make an inset in the wreath circle where the fruits will sit. I also made little swirls with the butter knife to make it look more wreath-like.
Once the creative crafting is complete (and it should not take too long), gently lift parchment paper with the meringue off the insert unto a baking tray and the pavlova is ready to bake.
Once pavlova is put in the oven, turn the heat down to 120C and bake for 60 min or until pavlova is pale gold & crisp outside and soft on the inside. (I know - you probably never know this on your first try. I baked at the lowest rack which worked well, so test with your oven)
