Instructions
Preheat oven to 120 degrees celsius.
Prep a piece of baking paper by placing a dinner plate on it and tracing around it. Flip the paper over. Put it on a baking tray.
Whip the egg whites in an electric mixer until thick.
Add the sugar a tablespoon at a time, ensuring to whip it in completely before adding the next.
Add the cornflour, vinegar and vanilla and continue to whip for a further 5 minutes.
At this stage the mixture should hold stiff peaks and be able to be turned upside in the bowl, if it can’t, whip it for a few minutes more.
Fill in the centre of the circle on the baking paper then move to the outer edges, trying to create a crown. Lift up the peaks with a fork to make them high.
Bake at 120 degrees for 1 hour then allow to cool in the oven with the door ajar for another hour.
