Pavlova

Why can't I make a pavlova. I make a beautiful sponge but when it comes to pavlova I just can't do it.

I had egg whites left over from making this yummy dinner last night. So I thought 'I'll give it another go'. I got all excited cause the mixture looked perfect as it always does if I remember rightly. Put it in the oven, followed the recipe perfectly and voila - look what came out of the oven - we had a pick at the edges as you can see . I was so disappointed. So that's it. I'm never making another pavlova in my life. I really thought I'd done it this time, but noooo.
