Molly,
This recipe came from my Grandmother through my mother, well tested

Whip six egg whites until they stand up on their own. Whilst beater is still on high add 1 1/2 cups of castor sugar a little at a time. Once combined drop beater to low speed and add eight drops of vanilla essence and 1 1/2 tablespoon of white vinegar.

Heap onto a pizza tin cover with aluminium foil and bake for 15 minutes at 350 degrees farenheit and then a further two hours at 200 farenheit. When baked turn upside down onto a plate and peel off aluminium foil. Top with bananas and then whipped cream or use any other fruit you like.

Hope these ingredients make sense in the US
