This recipe is from Mary Berry. Here is her recipe.
4 egg whites (at room temperature if you think of it, but not super necessary)
1 cup of sugar
2 tsp corn starch
2 tsp vinegar (like the stuff you use to clean. nothing fancy, just white distilled vinegar)
1. Start your 4 egg whites on slow speed. Gradually increase the speed until they are stiff-ish and cloud like.
2. While whisking at high speed, add your sugar one tsp at a time. Your egg whites will get beautifully shiny.
3. In a separate little bowl, mix the corn starch and the vinegar together. Then whisk them into your cloudy marshmallow.
4. On a piece of parchment paper, plop your cloud down and make it into a 9 inch nest, with the sides higher than the middle. The middle part of the nest will hold your whipped cream and berries after it's cooked and cooled. (I leave the whipped cream and berries off because everyone in my family likes to make their own, but that's not very pretty.)
5. Have the oven preheated to 320. When you put your pavlova into the oven, immediately reduce heat to 300 degrees.
6. Cook for 1 hour until its firm and lightly beige. Leave in the oven to cool. (or don't. I took mine out because I needed the oven for something else, and it was just fine!)
