You can use a piping bag with a smooth, large tip or two spoons for a more rustic-looking pavlova.
Make circles on the prepared baking sheet, several small ones (for individual mini pavlovas) or one large one. It can be round, square or rectangular.
Spoon a mound of meringue in the center of the shape you want to make and spread it carefully. Add more if you want a taller pavlova. Reinforce the edges if you want higher sides and a lower center (to encase the filling). Do it slowly and carefully so you can course-correct it.
Carefully transfer the sheet to the preheated oven and immediately lower the temperature to 230°F (110°C), very low.
Bake until the edges are firm and dry, but the center is barely soft to the touch. And, if handled gently, it begins to peel off the paper on its own when you lift it.
The baking time depends on the size of the pavlova, the oven and the humidity of the day, but it takes 1 hour at least for a medium pav. If it's your first time, it’ll probably take a few tries to get the desired shapes and baking times and create a perfect pavlova.
Turn off the oven and let it cool completely. I make it at night and leave until the next day. They might slightly crack as they cool, and that is normal.
