dont have a question but have an answer for anybody who wants to make this.
6 eggs (room temperature) 8oz caster sugar. 1teaspoonful vinegar (any colour) 1 heaped teaspoonful cornflour Separate eggs. Whisk egg whites until very stiff. Throw away yolks. Whisk in small taste of caster sugar at a time holding very high up until 8 ozs is gone. add vinegar and cornflour. Turn onto either greased plate and have oven ready at 150 degrees - keep that temperature and bake for one hour and 15 minutes. let me know how you get on.
You have just wasted six egg yolks ? Thrown them away ? To make a Pavlova ? Those yolks could have been used for something .You can freeze them or they will keep in the fridge for several days to be used in a sauce or something .How wasteful.
